So, here I am again. I have see so may stories of Percy choosing to be a god, but I wondered what would happen if he accidentally became one? Well, I am going to explore this idea in this story, but with a twist. All you need do is follow to see what happens next, so hop on board!

I do not own Percy Jackson or any of the characters in the Percy Jackson series.

The Last Birthday

Summer at camp half-blood is a time of joy and happiness for the campers residing there. But for the last four years they had been some of the worst, full of fear and war. When the war was finally over, a collective sigh of relief spread across the camp, enveloping it in a mist of complacence. Everything was fine, life was back to normal, and things were looking up for once. But something monumental would happen during the summer after the war that would rock the camp, indeed the entire godly community to its very core. An act that was so shocking that it would forever rewrite the books about mythology for generations. It would create and destroy, obliterate and reincarnate, erase and rewrite. And it all started with a party.

This is the story of the accidental deification of Percy Jackson.

Nico shuffled innocently through the completed courtyard of the cabins towards the Poseidon cabin, glancing about in a manner that was no way shifty. He hid behind his back a wrapped box that was in no way addressed to his cousin, Percy. That was just inconceivable. The courtyard was deserted, but there was still no way to know if someone was watching.

When he was within the last few meters, he burst into a sprint and bolted into the cabin, only the be caught in strong, large hands.

"Whoa there, death breath" Clarisse grumbled. She was in the process of blowing up another balloon when the young son of Hades had barged in.

"Sorry, but I had to get here in a hurry," he panted, "Just in case Percy saw me, or even worse, the Stoll brothers" he said, eyes darting around the room as if to make sure that they were not hiding in the walls.

Even Clarisse had to shudder at that thought. If the Stoll brothers learned that there was a surprise birthday party for anyone, much less Percy, who knows what they would do.

While the two demigods were shuddering at the thought, a busy Annabeth bustled over and started to scold them. "Nico, so nice of you to come by," she said tersely, ripping out of his thoughts. "You can place the present on the bed over there" she motioned. Nico did as she told him to, because he did not want to get Annabeth mad at this point of the decorating process.

Annabeth rounded on Clarisse, only to find her hard at work blowing up balloons. Annabeth nodded curtly at her, silently thanking Clarisse, and bustled off to the next thing.

The reason these three and a few other friends of Percy Jackson's were preparing for a surprise party was quite simple. It was nearly the end of camp, and this was the last available day to throw a party for Percy.

The party had been planed by Annabeth, who had realized that Percy had never had a real birthday party with friends. She talked with his friends, and they decided to do something about it. It was decided that they would throw a party for him on the last day of camp.

After they had obtained permission from Chiron and from Mr. D (reluctantly) they started to plan every Tuesday. The people invited were,

Annabeth

Thalia

Nico

Clarisse

Grover

Tyson

The party was small, but these were Percy's closes friends, the ones he had known since the beginning of his adventures.

By this time it was almost dinner and all the decorations were in place. There was a small pile of presents stacked up on one of the unused beds, and banners hung from the low ceiling of the cabin. At the other end of the cabin a large blue cake sat where the saltwater fountain had once. It was decorated in a seafloor motif, with frothy icing waves adorning the top. Magical sea creatures jumped in and out of the waves, making the illusion of the sea complete.

With the decorations complete, the five demigods left the cabin. Little did they know that they were spotted by the Stoll brothers as they left.

The two brothers were lining up their cabin when they glimpsed the group of people leaving the cabin.

"Hey Travis," Conner said, "what do you think they were doing in Percy's cabin?"

"I do not know brother," replied Travis, "But I think we should find out during dinner."

And so they agreed to go explore the cabin. With that they finished arranging the cabin into a strait line (or as strait as it could manage) and led the campers off to dinner.

After they had scarfed down their dinner, the Stolls excused themselves from the eating area and pretended to go to the bathroom. As soon as they were out of sight of the other campers, they broke into a sprint and ran to the Poseidon cabin.

When they looked inside, they were met with a great surprise. They did not even know that Percy had a birthday anytime soon. So to see all the decorations hanging in the cabin filled them with glee. The mischievous kind.

The Stolls ran out of the cabin and into the bathroom to confer, just in case someone else decided to leave the dinning area. As they stood at the sink pretending to wash their hands, Conner started. "So, it looks like Percy is having a birthday party." he said.

"Yea, and he did not invite us either" Travis pouted.

"Well, the least we can do is to leave him a gift." Connor suggested.

"But what would be a gift worthy of the great Percy Jackson?" Travis mused.

They sat in silence for a bit, listening to the water, before Travis snapped his fingers, spraying water everywhere. "Eureka!" he shouted.

"Bro!" exclaimed Connor, "You got water all over me."

Travis waved it off. "Nothing a few paper towels can't fix" he said. "Anyways," he continued with a grin, "I think our perfect gift lies in the basement of the Big House."

His brother looked at him dumbly for a few moments as he toweled himself off before asking "What kind of gift would be in the basement of the Big House?"

Travis rolled his eyes as he also toweled off his hands. "I'll show you after dinner. We have been gone to long to show you now."

Connor shrugged and they both returned to dinner.

After the meal was over and everyone was heading to the amphitheater, the two brothers stealthily ran off to the Big house to get Percy's birthday present.

The basement was an old structure that was filled to the brim with wine barrels. When they got down, Connor's eyes lit up and a wicked grin spread across his face, matching his brothers.

"This will be the greatest birthday party ever." Connor snickered.

Percy left the arena looking for Annabeth, having not spotted her after dinner. It was not like his girlfriend to skip the singing afterwards, but it had happened once or twice before. So he just shrugged and continued on to his cabin. Its not like he needs to see her every night anyways.

When Percy got back to the cabin, he noticed before going inside that it was totally dark inside. He frowned and out of habit pulled Riptide out of his pocket. The lights were never off while he was away because he liked to come back and see that there was nothing unusual. Even Tyson knew that.

With caution he pulled open the door and held up his sword to peer inside.

'SURPRI-Whoa!"

Nico's yell was cut short by Percy's sword cutting though the air right in front of his face.

"Nico," Percy breathed in relief, "wha-" This time it was Percy's turn to stop short as he gazed upon the decorations covering the cabin and his other friends jumped out and yelled "SURPRISE!"

Percy just stood there like a fool with his jaw hanging open. It was only after Annabeth came up to him and gave him a peck on the cheek and said "Happy birthday" that he realized what was going on.

"A birthday party?" he stuttered as every came out of their hiding places, "For me?"

Annabeth laughed. "Of course its for you, silly. Why else would we have it in your cabin?"

For a few more seconds he was still to stunned to say anything, then broke out in a grin.

"Well what are we waiting for?"

First thing on the list was cake and drinks. The cake had made by some minor gods on Olympus, so it had a boarder of ambrosia and nectar mixed into the batter, so it was extra tasty for the demigods. Thalia had made some punch to go along with the cake, and it also had some nectar mixed in with it. But the cake was to small for them to overdose on the food of the gods, so there was no worries.

Little did the party goers know that the Stoll's birthday present was lurking in the punch.

Being the jokers they are, the Stolls slipped some wine in the punch while the room was dark. They even infiltrated the backup punch with a bit more in hopes to find a group of passed out demigods latter that night. In their opinion, making a person look silly without any strings back to them was the best kind of prank.

After the cake and a few drinks each, everyone was feeling some sort of effect from the punch. The mood was light and happy, and even Clarisse was being more social to the others. They began to play games, such as telephone (with much giggling), charades (Tyson still did not get how to play), and a minor and short game of truth or dare.

The turning point of the night came when Thalia suggested that they play punch-pong. This was approved of greatly, as the drink was a big hit among all of them. Thalia and Annabeth were on one team, while Nico and Percy were on the other.

To Percy and Nico's disappointment, both girls were quite good at the game. Even when mildly intoxicated, they both were still quite coordinated. After the third cup Nico dropped out, saying that the nectar was to much for him, and that he needed to stop before he burst into flames. Percy also reluctantly quit at four, but was dissapointed that he was unable to score on his girlfriend. When he complained of this to her, she giggled "What, worried that you would be beaten by a girl?"

He sputtered. "No-I-its not-" finally he found his voice, "Its just so hard to lose to you all the time at some things."

She giggled again. "But you always win at swords. And being so hot."

He pouted though, reaching anger. "You know," he said, his voice raising, "I wish you could not focus so much on my looks. That is all you have complemented about me in the last three months, ya know." At the end of the sentence his voice slurred a bit, making him repeat himself again.

Annabeth looked at him with concern. "You never told me about this before now."

Now Percy's voice was much louder, attracting the attention of everyone around. "Well, you never gave me the chance now, did ya" he slurred, "you never thought about complementing what I was good at, or praised any of my accomplishments. I was just how good I looked while swimming, and how hot I was when I did anything."

At this point Thalia thought it prudent to intervene. "Whoa Perce" she said, "I think that you should probably settle down."

"Oh, now YOU think I need to settle down now?" He slurred, "Well fuck you, bitch."

And with that he took one more swig of punch.

The first sensation Percy felt was the burning agony spread from his lower back to the rest of his body. It was like he was being burned from the inside out, but the pain never touched his skin. He let out a howl as the pain increased and he fell to the floor. All his friends stared in astonishment, to drunk to realize what was happening. Percy placed his hands on his eyes and mouth, where the pain was escaping in rolling waves. The pain in his Achilles point grew to that of an inferno consuming his very being, destroying him from the inside out. When he removed his hands from his face, his friends gasped as his eyes and mouth were molten red, the color of lava.

Finally Grover had enough sense to tell some one to get Chiron, but by this time it was to late.

In a final earsplitting howl, Percy's form glowed white and exploded in all directions, leaving a room full of bewildered demigods and the essence of a former mortal hero.
