Percy and Annabeth have fallen into Tartarus. The five Demigods that are left on the Argo have only limited time to save Camp Halfblood, as well as Greece. Nico, the son of Hades, must help them to find the Doors of Death, before its too late.

The Fourth installment of the Heroes of Olympus series. I had been asked to go ahead and do the fourth book by my readers of my recently ended Mark of Athena fanfic. I do not know if Rick plans on using this title for the fourth book so do not assume. Rated T for violence, and cause I'm too lazy to change it. DISCONTINUED

As the enemies amount, the Romans and Greeks must put their pasts aside, and unite to conquer the giants' army, Gaea, and other enemies. Secrets will be unveiled, enemies made, and friendships shattered. No longer is any demigod, immortal, or mortal safe from mother Earth's wrath. Will the Mark of Athena, whatever it is, be able to stop her?

Hey. Hey, you. Click on that title up there. I know, you're thinking, "What? Another MoA fic? No way am I clicking that!" But seriously, click it. It's got humor, danger, mystery, Percy, Leo, Jason, Annabeth, Frank, Hazel, Piper, pairings, and some randomness, but whatever. The best MoA under the sun! Or under the FanFiction category. This one's different, I promise. NOW COMPLETE!

Hi! This is my take on all the campers of Camp Half Blood reading The Son of Neptune while it happens. I'm trying my best to follow the timeline in the story. Read and Review please! enjoy! T just to be sure.

My own Version of Mark of Athena! I don't own the series or the characters!

Done to death, but everyone does it at some point. Percy Jackson's disappeared, but now Jason, Piper and Leo, along with other campers read the Percy Jackson &the Heroes of Olympus series.
