I recommend this book for: grade 5 and up
Oh, how I love this series! I devoured The Lightning Thief and The Sea of Monsters, and volume 3 doesn't disappoint, delivering the same modern twists on Greek mythology, exciting escapades, and hilarious narration as the first two. This adventure is darker, as befits an aging Percy and a world on the brink of war, but the humor keeps it from being scary. Percy, Thalia, Grover, and two of the Hunters of the goddess Artemis are on a rescue mission to save the goddess and Annabeth from the clutches of Luke and Kronos. They meet up with new enemies, including zombies raised from dragon's teeth (commonly mistaken for those of the T-rex), and for the first time, the group suffers losses.
Things that are done really well: Percy's awkwardness around Annabeth, the introduction of the Hunters and their "no boys allowed" philosophy, Thalia's character development, capturing the adolescent sense of humor, tying in myths that are new to the series, plus tying back to past events like the Lotus Casino. And my favorite scene, where they visit Hoover Dam, is sure to make middle schoolers laugh out loud - I did! So basically, I'm devastated that this book only came out a few months ago and I'm going to have to wait for #4!
