"The Lightning Thief" by Rick Riordan
(from the back cover)
Percy Jackson is about to be kicked out of boarding school.......again.And that's the least of his troubles. Lately, mythological monsters and the gods of Mount Olympus seem to be walking straight out of the pages of Percy's Greek mythology textbook and into his life. And worse, he's angered a few of them. Zeus's master lightning bolt has been stolen, and Percy is the prime suspect.
Now Percy and his friends have just ten days to find and return Zeus's stolen property and bring peace to a warring Mount Olympus. But to succeed on his quest, Percy will have to do more than catch the true thief: he must come to terms with the father who abandoned him; solve the riddle of the Oracle, which warns him of betrayal by a friend; and unravel a treachery more powerful than the gods themselves.
This is the first book in the series. There are 5 books in all. I love Greek Mythology books and I was thrilled when I read about this book at another book blog. I was at our school book fair a few weeks ago and they had all 5 books and I bought them all. So you will be seeing the rest of them popping up here.
Percy, Grover and Annabeth are on a quest of find the lightning bolt. Along the way they run into several bad people the the God's have sent, but which God it doing all this? That is the question of the day. Percy starts out at Half Blood Camp, a place for kids that have a mother or father for a God. There Percy meets Annabeth and several other campers. Percy has killed the Minotaur that killed his mother. He is hurt and taken to the camp to recover. This leads to his visit with The Oracle. And sends him on his quest!
