Watson created the idea of The 39 Clues: Cahills vs. Vespers, The 39 Clues: Unstoppable and The 39 Clues: Doublecross. She collaborated with the four original authors (Rick Riordan, Gordon Korman, & Peter Lerangis) on creating Vespers Rising, the segway between the Clue Hunt and Cahills vs Vespers series.
