Author's note: I don't own Percy Jackson and the Olympians.

I got this idea and wanted to see if I could write it.

Sally looked at the two black hair boys, eating blue, blueberry pancakes for breakfast. She yawned as both boys looked up at her. Her son, Percy smiled at her. His younger cousin Nico, mean while looked apologetic at her. He had arrived at 2am by shadow-travel. Sally usually didn't care when he visit (although he had a habit of stepping out of the shadows and scaring her), except last night he had crashed into a chair waking the whole household. She was tired for this reason. Nico had turned up after another fight with his Father, Hades and Step-mother, Persephone.

"What are you two going to do today?" Sally asked ruffling Nico's hair. She laughed at the annoyed look she received from the young boy.

"We're meeting Thalia and going to the public pool," said Percy looking excited. Nico didn't look as interested and he pulled a face.

Percy left the room to get his stuff together for the day. Sally walked to the closet and pulled out some items and gave them to Nico. They were a towel, sunscreen, board shorts and bathers. She smiled at the young boy.

"Thought you might need these, especially if you spend time with Percy," she said.

"Thanks," said Nico giving her a quick hug, before pulling away looking embarrass and upset.

"You better hurry, Percy should be ready soon. You don't want to keep him waiting."

Nico nodded, hurrying to get ready. Percy was wearing a sea green shirt over kaki shorts. Nico was wearing black shorts and a black button up shirt with gold buttons. His skull ring was on his hand. Percy had his stuff in a bag. Nico had his towel over his shoulder. They left the Jackson-Blofis residence soon after to meet Thalia.

Thalia met them at the coffee shop a couple of blocks from the public pool. She was dressed in her Death to Barbie t-shirt and a black skirt. On her head was a silver tiara. She was drinking a chocolate milk shake.

"Hey cousins, how are you? She said pulling Nico into a friendly headlock. Nico squirmed in her arms until she let him go, he then proceeded to glare at Thalia. Thalia just laughed to him.

"Hi Thals, we are good. Let's go" answered Percy after giving her a quick hug. They quickly walked to the public pool. They found a spot on the lawn that surrounded the pool. They spread their towels out and dumped their stuff. The three cousins headed to the pool for a swim. Thalia and Nico weren't strong swimmers (when your children of Zeus and Hades you usually stay away from water), so they stayed in the shallows.

Later Thalia was laying on her towel sunbaking. The sunshine was beating down; Apollo was doing a great job today. Thalia was reading (a book in Ancient Greek that she had borrowed from Annabeth). Percy had gone to ring Annabeth to see if she would come and join them (She needed a break from designing Olympia). He also decided to get something for them to eat. Nico had wandered closer to the pool and was watching a group playing.

Suddenly Nico was pushed into the pool. He was held under the water. Nico thrashed as he tried to get away from what held him under. He had no idea who was holding him under or why. He wondered if anyone up top had noticed what was occurring deep underwater. He couldn't breathe, his chest was burning. His lungs were screaming for air. Only moments before he had watched the last bubbles of air escape from his mouth and slowly rise to the surface. Nico needed to breathe, he trashed and pushed upwards but the hands holding him under wasn't letting up, pushing him further down into the salty water.

By now Nico wondered if the public swimming pool was part of his uncle Poseidon's domain, they all knew that the big three gods didn't like their brother's demi-god children entering their domain. His ADHD brain was wandering he had to remember that he was drowning!

Nico couldn't break away from the arms holding him under. He had to breathe. Although he tried to fight the urge he couldn't stop the natural yearning. He HAD to breathe. He took a breath; water rushed into his mouth, the salt water burned his lungs. He slowly started to loose consciousness. Nico usually wasn't frightened of shadows and darkness but now he was terrified as he slipped down to the dark bottom of the pool.

The last thing Nico remembered was drifting into the depth of darkness. He thought he could see the outline of Thanatos in the darkness, but that couldn't be right. He wasn't dying, was he?.

Percy arrived back to where Thalia was sitting. Annabeth had declined to come. He came back carrying three hot dogs. He handed a hot dog to Thalia and looked around for Nico. He couldn't see him and was annoyed, he was gone for a minute, and when he came back Nico was missing.

"Nico," he called out drawing looks from the others at the pool. Thalia looked up from the eating. Nico's clothing and skull ring was still where they had dumped their towels (so they knew he hadn't left, he wouldn't leave without that ring). Where was he? Percy scanned the crowd before noticing a group of teenagers in the deep end. Nothing was unusual about the group, except they seemed to be pushing something down towards the bottom of the pool. Some how Percy knew that it was Nico, he didn't know why he just did. He ran towards the deep end screaming out Nico's name before diving in. Thalia also raced to the side of the pool.

Percy used the water to propel himself towards the teens. How dare they attack a twelve year old, they were all older then him. He grabbed the closest one and pushed him under, before concentrating on reaching Nico. Unfortunately the group turned on him; however they were no match against a son of Poseidon. Percy caused a huge wave to distract them (it slammed the gang into the opposite wall). It was long enough for Percy to bring Nico to the surface and close to the edge of the pool. Thalia was within reach to help him pull an unconscious Nico out of the pool. Water poured off Nico while Percy got out of the pool dry. Nico wasn't breathing. Both Thalia and Percy thought he looked so small and little. Percy immediately began mouth to mouth.

"He has water in his lungs," said Percy "I'm gonna try to draw the water out, hopefully it works." He concentrated on the salt water he knew was in Nico's lungs and visualised it coming out of his mouth. Meanwhile Thalia checked his pulse. There was no pulse.

Thalia began CPR. She compressed Nico's chest and heart as taught in the first aid course the Apollo campers had run. Both Percy and Thalia were quietly praying to Apollo, Hades, and their Fathers; to all the gods that Nico would start breathing. Thalia was just repeating 'help us, insert gods' name' in her head over and over.

"Percy it's not working" Thalia said with tears running down her cheeks.

"He can't die."

They knew they were loosing him. They needed to jump start his heart with a defibrillator, which they didn't have. Thalia knew that an electrical pulse to the heart could get it to start.

"Percy move away from Nico," said a hysterical Thalia

"WHAT?"

"Just do it" She shouted.

Percy was shocked was Thalia giving up. He moved slightly towards her, as he did so he was no longer touching Nico. Thalia had an idea, She JUST HOPED IT WORKED. She placed her hand on Nico's chest- just above his heart and sent an electrical shock into his body. Nico body jerked forward. Percy was startled but realised what Thalia had done and checked his pulse. He shook his head. Percy had tears in his eyes. Nico was NOT going to die. Thalia looked towards Percy her eyes seemed to ask should she try again. Percy nodded he couldn't see why not. Nico's body jerked forward again when Thalia shocked him. Percy checked his pulse again and a huge smile lit up his face. Nico had a pulse, his heart was beating again. Percy continued mouth to mouth but they soon noticed that Nico was slowly breathing. He was alive.

The paramedics arrived then. Some bystander or maybe the lifeguard (who was still trying to work out how the huge wave had occurred) had called them. Percy and Thalia stepped back as they quickly hooked Nico up to Oxygen and made sure his heart was beating with monitors. Apparently the mist had hidden the shocks Thalia had delivered to his heart. They both were thankful to the mist. The mortals also didn't realise that Percy had exited the water dry. The paramedics loaded Nico onto a stretcher and they all headed to hospital.

Last minute comment: Well there you have it. I killed Nico. Okay just for a little bit. I think I may write about the fall out of what happened. But only if you want it. So please review.
