This is just a fanfiction. If you haven´t at least read Percy Jackson and the Olympians and Heroes of Olympus, you probably won´t understand half of the story.
The story will be written focusing on different characters every so often (Heroes of Olympus style).
This is my first time publishing a story so I'm still getting acquainted to the controls. Also, English is not my native language and I would like if you pointed out any mistakes in the reviews. I'll post a couple of chapters and see how they're received. If the reaction is good, I'll continue to post regularly.

I appreciate any reviews and ideas.

Now, on with the story.

Chapter One

PERCY

How long had it been? How long since the love of his life had been taken away from him? How long since Annabeth had died?

A year. This exact same day, a year ago, one of the most powerful demigods ever, one of the seven from the Great Prophecy who defeated Gaea and the Giants, had died in a car accident.

Stupid drunk driver. He was so wasted that he didn't notice he was driving on the wrong side of the road. Annabeth still tried to veer but the drunk man slammed into her door. She died; the drunk driver survived. Percy wanted to kill him. But the anger he felt was quickly replaced with self-loathness.

"If I had been there…" he thought to himself "I could've done something."
Not a day went by that he didn't thought of this.

Two days later, a ceremony was held at Camp Half-Blood. Camp Half-Blood and Camp Jupiter were there in weight; Carter and Sadie Kane, Annabeth's and Percy's egyptian magician friends were there also present; Annabeth's father, Frederick, along with her stepmother and half-brothers; Annabeth's cousin, Magnus, the Norse demigod and einheri (meaning he died and was brought to Valhalla, so he could fight as one of Odin's warriors in Ragnarok - weird, right?); the Hunters of Artemis, led by Thalia Grace, one of Annabeth's oldest and closest friends, who was almost as heartbroken and sad as Percy; and, of course, every Olympian God with a cabin in camp (including Hera, to everyone's surprise).

Hades himself conducted the ceremonies, helped by Thanatos. In the huge crowd, rare were the faces clean of tears., but none like Athena's and Frederick's. Percy sat in a corner, shocked. Thalia did her best to comfort him but she too was badly shaken. Then, Hades made an announcement:

-Due to the great feats and accomplishments of this brave demigod, the Judges and myself have decided to grant Annabeth Chase, daughter of Athena, direct entrance to the Isles of the Blest.

Even Percy had let out a cheer at the time.

After a few speeches, it was time to burn the Burial Shroud. It was beautiful: a long, grey sheet with a big owl, Athena's sacred animal right in the middle. There were representations of Annabeth's greatest achievements embroiled in the fabric: a small labyrinth with the Greek delta in it; a replica of the Argo II; a small Athena Parthenos; even a golden laurel with the letters SPQR beneath it, the symbol for Camp Jupiter, courtesy of the Praetors Frank and Reyna.

Three people came forward to burn it: Athena herself, Frederick and Percy. Together, they lit the shroud using the torches they had in hand. They stood watching as the ashes rose in the starry night sky. At the same time, Hephaestus' kids from cabin nine shot a bunch of firecrackers into the sky, which exploded to reveal moving images of Annabeth's most marking moments at camp. Percy got teary eyed when he saw the two of them kissing at the bottom of the canoe lake.

After that, everyone started leaving. Percy stood by the hearth until Apollo's sun chariot started its journey across the sky. Leaving, Percy turned to see a little girl in the early daylight, tending the flames of the hearth. The goddess Hestia looked at him and shot him a wry smile, but Percy couldn't bring himself to smile back. Not with all the pain in his chest.

He went towards his cabin: cabin three, Poseidon's cabin. He was the only regular camper to stay there but his half-brother Tyson, the Cyclops, would share it with him when he came to visit. This was such a day. The big guy's pillow was wet from crying. Annabeth was a good friend to him to.
Finally, Percy laid down and let all the pain out of his mind as a baffled scream. After a while, he fell asleep crying for his beloved.

And today, a year had passed. The pain was still there, although it was a tiny bit weaker.
After three months of begging, Percy had finally convinced his cousin Nico, son of Hades, to agree to his demands.

Preparing himself to what could be the last hours of his life, the hero of Olympus walked out of his cabin, a low, sea-green building with corals in the windows, sea-shells incrusted in the walls and tridents hung up on the door.
Steeling his resolution, Percy walked towards cabin thirteen, Hades' cabin. The black obsidian building reeked of death; the path leading to the entrance were littered with bones and jewels; the green flames in the braziers shot long shadows across the path; the black stygian iron doors were topped by white skulls.

Percy knocked and the door opened, revealing Nico DiAngelo, the single occupant. He was sixteen, three years younger than Percy. He had a pale constitution and black hair, like a raven's feathers. His once dull eyes were full of life and joy. Kind of ironic seeing he was the son of Hades, God of the Dead.
When he saw Percy, his eyes faltered for a moment.

-Are you ready? – asked the son of Poseidon

-I'll ask you one last time, Percy. Are you sure you wanna do this?

-Tartarus himself would kneel to the gods before I went back with my decision.

Nico seemed satisfied with this answer. Percy knew first-hand the ruthlessness of the pit god as he had fought him when he fell there with…Annabeth.

Grabbing Percy's shoulder, Nico warned:

-Hold on!

And they slipped into the shadows.
