I started The 39 Clues series several years back, but never finished, so I thought I would give it another go. Book One: The Maze of Bones is written by Rick Riordan of Percy Jackson fame. The series pits members of the Cahill family against one another in a search for clues, the ingredients for a mysterious but very powerful serum. I enjoyed the scavenger hunt aspect of the story, though it tended to be a little dramatic. I love the idea of different YA authors for each book. Has anyone made it through the entire series and if so, what did you think?
