The 39 Clues Book One: The Maze of Bones lets you know two things: there are 39 clues, and this book will lead you somewhere called the Maze of Bones.
It's no trick. Both those things are true. Amy and Dan decide to undertake their grandmother's quest, a trek around the world in search of 39 clues. The first clue leads them to the Catacombs of Paris, a place where they moved the skeletons of the dead when cemeteries became over-crowded, giving it the nickname the Maze of Bones. If you couldn't figure that out, you'll going to need a lot of help making it to clue number two. Don't worry; Shmoop's here to save the day.
