If you need a good read with some action, mythology and some jaw dropping twists and turns, I highly recommend the Percy Jackson and the Olympians series by Rick Riordan. I could not put them down. Amazing story teller that makes Greek mythology come to life in beautiful ways. You can get it cheap on Kindle (a favorite of mine! iPhone app or kindle) for $4.40. Or pick up a paperback for $5 and you won't be dissapointed.
