Consumption by PsychoMike5469 reviews
This is my first Fanfic ever and would greatly appreciate some feedback. Something ancient is stirring, something that is far worse that anything anyone in the PJO universe has ever encountered. Slight Gears of War as well.

Sons of Chaos by Bryce Gray reviews
Ok i know this type of story has been overdone but i tried a different spin on it. Annabel doesn't cheat on Percy, and Percy's friends don't abandon him. he also doesn't hate all of them. so pleas read and review. let me know what you think rated t to start but will turn to M for graphic content and swearing. No lemons or smut. characters are a bit ooc slight crossover. mostly PJ&O
