The Sea of Monsters - Rick Riordan Extra star for the use of the Nobody story from The Odyssey as well as the Sirens story.

See my review of [b:The Lightning Thief|28187|The Lightning Thief (Percy Jackson and the Olympians, #1)|Rick Riordan||3346751] for everything else I thought.

Again, an enjoyable, but not top notch YA fantasy novel.
