The Medusa Plot
The 39 Clues: Cahills vs. Vespers #1
by Gordon Korman

My rating: 4 / 5
Genre: Middle grade mystery, adventure

Spoiler notice: The following review may contain some spoilers for the previous books in the series, starting with The Maze of Bones.

Two years after the events at the end of the main series, we pick up with Amy and Dan, trying to live a “normal” life. For Amy, this means dating a guy at school while secretly training in various disciplines at home. For Dan, this means the drudgery of normal school, but he’s also dealing with some internal distractions. When the Vespers make a move after 2 years of silence, it’s a big one. Now Dan and Amy are in a race against the clock to save some of their closest loved ones and some of their once-worst enemies.

This follow-up series to The 39 Clues starts off with a bang. Despite the hatred that these family members had for each other in the past, I think the ending of the main series was sufficient to pave the way for these young people working together now. And the fact that their parents aren’t necessarily on board with inner-Cahill-family friendship seems quite realistic as well. I particularly like that Sinead lives with Dan and Amy now and has established a com-center at their house. The way this generation of Clue hunters works together is nice to see.

Dan seems to have a sort of PTSD, where he’ll pull away from Amy and kind of recede into himself. She doesn’t know that he’s mentally working out how he can complete and use the serum that was destroyed (everywhere but in his memory) 2 years ago, so he can stop the Vespers. I really appreciate this aspect of the story and feel for these siblings who have already been through so much tragedy and just want to keep their loved ones safe.

I feel like, in some ways, the story has aged and matured past where it started. The original series could be read by as young as 10-11-year-old kids, but this series, so far, seems a bit darker and more mature than that. If kids sort of “grow up” with the series, though, and start this series after reading the first, at around 12-13, I could see it working. For my part as an adult reader, I enjoy the new, deeper elements to the plot and look forward to seeing where the story goes from here.
