I am on the third book currently and I am completely enthralled by this series. I know many people like the Harry Potter Series (I never read the books) or the His Dark Materials Series (read book 1 and 2), but for some reason I find these books quite entertaining. More so than His Dark Materials and at least on par with Harry Potter. I think Harry Potter has better villains but other than that I am loving this series. Synopsis: Percy Jackson is a half blood. A term used for Half Human Half God mortals.His father happens to be Poseidon and the 5 books series surrounds his adventure leading up to a prophecy that is supposed to be fulfilled once he turns 16 years old. Throw in greek mythology in a world of the 21st century and you have entertainment for weeks on end.
