Book 2 of the Heroes of Olympus series
Percy Jackson is back! Only, he doesn't remember anything about himself except his name and a vague memory of Annabeth. After spending time on the west coast with a pack of wolves, he arrives at a camp for demi-gods. He knows this is where he belongs but it doesn't feel quite right. He quickly falls in with a pair of mis-fits who are fairly new to the camp. Soon, they are tasked by the God of War to take on a quest.
As the quest continues, Percy's memory slowly comes back as the horrors of what is to come unfold before them. These three unlikely heroes must join with others to save the world - again.
I am looking forward to the next installment in this series.
