Percy Jackson appears to be an unremarkable boy who's only strike against him seems to be getting into trouble and getting kicked out of boarding school each year. His class visits the Metropolitan Museum of Art to see the exhibit of Greek and Roman art and Percy can't believe it when his teacher attacks him. When it's all over, no one ever remembers there being a Mrs. Dodds.
Percy's mom decides it's time to send him to the camp his father has always wanted him to attend. Percy appears at the boundary of Camp Half-Blood after watching his mom die and killing a Minotaur. The camp is filled with demi-gods or half-bloods--children of the gods. Before Percy knows it, he's sent on a quest to recover Zeus' lightning bolt--which the gods think he stole.
A great first book in a series. The characters are pretty well-developed, and there's plenty of background to inform anyone who doesn't know their Greek mythology very well. All of the Olympians come into play in one way or another, and Percy's adventures as he crosses the country in 10 days are amusing. Lots of action and adventure to support his quest. I can't wait to read Sea of Monsters, book 2 of Percy Jackson and the Olympians!
