The Medusa Plot is the first book in the second series of The 39 Clues, Cahills vs. Vespers.
Thirteen-year-old Dan Cahill and his older sister, Amy, thought they belonged to the world's most powerful family. They thought the hunt for 39 Clues leading to the source of that power was over. They even thought they'd won. But Amy and Dan were wrong.
One by one, distress calls start coming in from around the globe. Cahills are being kidnapped by a shadowy group known only as the Vespers. Now Amy and Dan have only days to fulfill a bizarre ransom request or their captured friends will start dying. Amy and Dan don't know what the Vespers want or how to stop them. Only one thing is clear. The Vespers are playing to win, and if they get their hands on the Clues... the world will be their next hostage.
Tropes:
- Downer Beginning: Once again, this book (and the second series) starts with one, which is the capture of the seven Cahills by the Vespers.
- Hypocritical Humor: At one point, Hamilton Holt complains that "Those guys ripped off what we rightfully stole!"
- Your Princess Is in Another Castle!: After Dan, Amy, Hamilton and Jonah steal Caravaggio's "Medusa" and deliver it to the Vespers, you would expect the novel to end at the halfway mark, right? Nope, the "Medusa" they stole was actually a fake, and the novel's remainder has them try to find the real one instead.
