I love all of the Percy Jackson books, but I have to say that The Sea of Monsters isn't my favorite. Mostly because Grover isn't in it as much (him being goatnapped and all). While I may love Percy and Annabeth I was not so thrilled to see that Grover wasn't as much of a part of the adventure. However Clarisse was a great addition to the story. She has that whole "Daughter of Ares" thing going for her.
