The Mark of Athena
By Rick Riordan
Disney/Hyperion Books, 2012. 586 pgs. Young Adult
As the third book in the Heroes of Olympus series opens, Annabeth, Jason, Piper, and Leo are flying aboard the Argo II into enemy territory--the camp for the Roman half-bloods. Although they manage to successfully find Percy Jackson, along with two new friends of his, Hazel and Frank, they also inadvertently attack the Roman camp, which leads to the Roman half-bloods setting out to destroy the Greek half-blood camp, which fits in nicely with Gaea's plan to cause chaos and war among the demigods. Added to this complication is the prophecy of seven, and Annabeth's disturbing conversation with her mother, Athena, who has sent her on a quest to avenge her. The seven demigods must figure out what Athena even wants from Annabeth, save Nico di Angelo, who is being held captive by two of Gaea's minions, and try to figure out how to stop Gaea's return.
Another exciting novel from Riordan. Told from the viewpoints of four of the seven demigods, readers get a chance not only to follow along with the action but also to experience the characters' fears and insecurities. Per Riordan's usual style, there's enough humor, adventure, and interesting twists to keep readers going through nearly 600 pages of reading...and longing for the next book in the series.
