Max Whitfield and the Sea of Monsters

Last time you heard the story about how Percy Jackson, Annabeth Chase, Grover Underwood and Penny Ranger retrieved Zeus's master bolt. But their story doesn't end there. They'll be going into uncharted waters now. So it's a good thing I'm coming along this time.
My name is Max Whitfield, son of Hermes, and this is my story.

This is a sequel to "Penny Ranger and the Lightning Thief". If you haven't yet, you should read that book first.
