The Sea of Monsters by Rick Riordan
A little note of disclaimer on this book, it is the second in a series and I just realized I never reviewed the first book, The Lightening Thief. The first book is awesome and a great read for middle schoolers on up. I especially like to recommend it to my boys who are a little reluctant to read.
This book picks up about a year after the last one. Percy Jackson, our hero, is a demigod or hero (the son of Poseidon and a mortal woman). Percy spent the first twelve years of his life not knowing his true identity, that is until a centaur and a satyr found him and brought him to Camp Half-blood, a summer camp for demigods.
In the first book, Percy goes on a quest with his satyr pal Grover and another half-blood named Annabeth to retrieve the lightening bolt of Zeus. Now, Percy must save his beloved camp as well as his best satyr friend. With the help of Annabeth and a baby cyclops, Percy journeys into the Sea of Monsters to save Grover and bring back the one thing that will save the camp.
Deterring Percy on his quest is the new activities director for the camp, Tantalus, and an evil half-blood named Luke. Percy also faces his normal disadvantages, such as being unlucky and dyslexic, not to mention being one of the least favorite person of some of the gods. Did I also mention all the monsters he will have to face along the way? Hey, it is all in a day's work for a thirteen-year-old hero.
I really enjoyed this book. I find Percy to be an every man's hero and a good role model to kids who may feel like they don't fit in or who struggle academically/socially. I once again recommend this book to middle schoolers on up (upper elementary would probably enjoy it as well).
