A few months had passed since the giant war, Halloween was three days away but there was nothing to be happy about. Just yesterday two giant scorpions had attacked Camp Half-Blood and to everyone's surprice they had managed to end the life of camp's biggest hero, Percy Jackson. He had put quite a fight there, but in the end while he had managed to kill one of them with his ever-trusty sword Reptide the other one stung him directly in the hearth when he least expected it. So today was a very sad day at Camp Half-Blood especially for a certain son of Hades. Nico di Angelo had been crying non-stop since yesterday, after all his one and only Sea Prince was dead. Sure Annabeth had been Percy's girlfriend, sure Nico had Will but the feelings Nico had for the son of Poseidon were stronger than any of that and having had to watch the beautiful boy die just made him realise that even more. So there he was in cabin 13 sitting on his bed in his black satin pyjamas, with his head buried in his knees, crying. His longish shaggy hair was a mess, his eyes were redder than a baboon's ass and his breath stunk worse than a can of expired anchovies, but none of that mattered, nothing mattered anymore.
"Nico!" - someone yelled at him. He recognised that voice all too well. He lifted his head and there he was, Percy Jackson, wearing his orange Camp Half-Blood t-shirt,a pair of blue, baggy jeans and flip flops, his longish black hair and sea-green eyes as beautiful as the first time the son of Hades had laid his eyes on them. But there was something different about Percy, he was transparent.
"Perce! How? Shouln't you be in the underworld?" - asked the Italian in both surprice and joy.
"I was hoping you could tell me that, Ghost King. After I died I went to the underworld but then there was a purple flash and the next thing I knew I am here but no-one besides you seems to be able so see or hear me." - explained the Sea Prince. Nico thought for a moment and then he told Percy to stay put and started dressing himself. He put on a long sleeve black v-neck, tight black ripped jeans and black leather combat boots. He went to his bathroom (yes, cabins had them after Leo was done with them), brushed his teeth and shadow travelled. He wanted to ask his half-sister Melinoe, the goddess of ghosts about Percy but the shadows took him to Hades instead.
"Dad...?!" - asked the olive-skinned boy in surprice.
"Hello son, let me guess you came here to ask about Poseidon's brat?" - smirked Hades, unimpressed.
"How would you know that unless you had something to do with it?" - asked the Ghost King angrily.
"Well, Nico you know that I want to make you my immortal heir, right?" - asked the Underworld god.
"Yeah, but what has that got anything to do with Percy?!" - asked the Italian, getting a little impatient.
"Well you see, contary to popular believes I do want my children to be happy so I thought to myself would I be able to see you sad for all eternity if I don't do everything that's in my power to save your true love, regardless of my feeling for him. Next thing I knew I was bounding his soul to the living world." - explained Hades.
"You know about my feelings for Percy?!" - asked Nico embarrassed.
"Of course I do and I approve, the Underworld would benefit from an alliance with the Sea." - said Hades. Nico hugged his father which was kind of new for both of them.
"But, wait a minute he's still dead!" - realised Nico.
"You can ressurect him and make him immortal with one move and if you do that I made a deal with the Fates to make you immortal. I can only give you two clues: Halloween and Glaucus. Oh and don't worry I will help you with your love-life If your friend Jason doesn't beat me to it. Now go, tell your crush the good news!" - said Hades amused.
Nico shadow travelled back to his cabin. There was ghostly Percy lying on his bed. He got up into a sitting position once he saw that Nico was back.
"Did you find out anything?" - asked Percy anxiously
"Melinoe said that for some unknown reason you are stuck here." - lied Nico.
"So there's nothing anyone can do?" - asked Percy with ghostly tears in his eyes.
"I didn't say that. You can be brought back but you will become immortal." -explained the son of Hades.
"Well since I have no other choice, lets do it!" - decided the Sea Prince after thinking for a few minutes.
"I only have two clues: Glaucus and Halloween." - said Nico.
"I've heard of Glaucus, he became immortal after he ate some grass from Gaza." - explained Percy.
"Hold on, the veil between the living and the dead is so weak on Halloween ghosts can even EAT! All we have to do is get that grass!" - Nico explained in his Eureka moment.
"Wait I am a ghost, I can't fight, we will need to take someone else with us!" - said the son of Poseidon.
"Let's take Jason that way we won't have problems with our "dear" uncle Zeus!" - suggested Nico.
"Good idea!" - said Percy. If only he knew the real reason Nico suggested Jason.
"We also have to tell your parents." - realised Nico.
5 minutes later Nico was knocking on the door of Zeus' cabin and Jason let him in. Nico explained to the blonde the whole situation including that he chose Jason so that he can help him make Percy his. Jason hesitantly agreed and they decided to leave camp the next morning.
It was a very quiet evening at the Blofis' appartment. Sally was crying on the couch next to Paul when out of the shadows Nico appeared. He explained his plan to the Blofises.
"Nico you know it would be cruel if you were lying!" - said Sally.
"Don't worry Mrs. Blofis, no matter what I will bring Percy back!"-said Nico with determination in his eyes and recieved a hug from Sally. He was so not used to hugs.
