The Titan's Curse (Rick Riordan)

This third installment in the Olympians series is very much like the first two. Percy Jackson, half-blood son of the god Poseidon, has to face mythical monsters and rogue Titans to save his friends and, oh yes, the whole world. This time the goddess Artemis and Percy's good friend, Annabeth, have been taken hostage and have to be rescued. The author is doing a good job keeping the stories interesting and exciting, but they are for teenagers and, for me, are getting a little stale. I still like them enough to want to keep reading, but need to wait a while before reading the next one.
