This middle grade book would have been one of my absolute favorites in my youth, and I loved it now too. I love Greek mythology, and this is basically Greek mythology meets modern urban fantasy.

Perseus Jackson, short Percy, is a problem student who can never settle down anywhere. His mother lives with his detestable step-father in New York, and he gets moved from boarding school to boarding school. But one day something changes, when his math teacher turns into a Fury and tries to attack him. He eventually finds out that he is actually a demi-god, the offspring of Poseidon with his mortal mother, and that there's a whole camp full of children like him.

But war is brewing amongst the three major gods Zeus, Poseidon and Hades because Zeus' bolt was stolen, and Percy is sent on a quest with Grover the Satyr, and Athena's daughter Annabeth, to retrieve said bolt before the summer solstice.

The story is fast-paced, pretty fun, lots of monsters, and I read a beautifully illustrated edition. Would recommend for any child that shows a hint of interest in mythology. I'm not a child, but I'll keep reading too. :-)
