A nice little companion to the series, though I felt it lacked something. I don't know. It sort of seemed like it was just thrown together--a few short stories Rick Riordan wrote on a rainy day, conversations that surely took even less effort, a rough map of the camp, a picture of what Annabeth's trunk looked like, some puzzles in the back, and some professionally drawn, full-color pics in the middle of some of the characters of the series. It seemed to me like something that took less than a month to make, and was sort of a spur-of-the-moment thing. But, I don't know. The stories were kind of exciting, I guess, just nowhere up to their usual standard in the actual series, though the last one, The Sword of Hades, was pretty close.
