The Lightning Thief (YA)
This is the first book in a young adult series. I am really glad I saw the movie before reading the book--otherwise, I would have hated the movie. The movie left out tons of book action! In the book, Percy Jackson discovers he is a demi-god: half human, half god. He goes to Half Blood Camp to figure out which god is his father and after that, he is sent on a quest. His quest is to find the stolen lightning bolt of Zeus and return it to the mighty god. This book had tons of action, great characters (I loved Grover--Percy's protector who is a goat disguised as a human) and a lot of humor. I have the rest of this series on my Kindle and look forward to reading them. These books can span the YA audience and adults could love them too.
