I did enjoy The Puzzle Master, though I also had some issued with it. What did I think of this next installment in the series? Check out my Review with Spoilers for the Puzzle Box by Danielle Trussoni!

The Puzzle Box by Danielle Trussoni: Jen’s Quick Take
- Published on October 8, 2024 by Random House; 336 pages
- A fun thriller format perfect for fans of books like The Da Vinci Code
- Set in Japan, this book features protagonist Mike Brink attempting to open a legendary puzzle box that has remained unsolved since the 1800s.
- The Puzzle Box ditched the plot elements (weird insta-love, excessive info-dumping, haunted dolls) that I felt detracted from the story in The Puzzle Master
- Do you have to read The Puzzle Master before The Puzzle Box? While the books share some recurring characters, I think you can read The Puzzle Box on its own!
Review of the Puzzle Box With Spoilers

If I think an author has something interesting to say, I will never give up on them after one book.
I felt that The Puzzle Master incorporated a few too many ideas (the cypherpunk movement, Bitcoin, telepathy, Jewish mysticism, feminine mystery cults, demonic possession, and a haunted doll, to name a few.)
Plus, I took issue with the instalove: the fact that the main character, a super-analytical guy who designs puzzles, meets and falls instantly in love with a woman locked in a psychiatric hospital for murdering her boyfriend.
But it was almost as if the author of The Puzzle Master read my mind (I think book one also had a telepathy angle!), because The Puzzle Box has none (well very few) of these elements. And NO haunted doll!
What did The Puzzle Box have?
- A fast paced escapist plot with a lot of action
- More focus on Mike and less on romance and niche intellectual issues
- A deep dive into Japanese history, including a fascinating deep-dive on gender and royal succession in Japan
- A great travelogue around Tokyo, Kyoto, Edo, and Kyushu
- References to The Da Vinci code (which this book definitely reminded me of!)
What Happens in The Puzzle Box by Danielle Trussoni?
- Mike and his dog Connie are back
- He’s invited to fly to Japan to try to open the Dragon Box, a legendary puzzle box created at the beginning of the Meiji period, a time when Japan transformed from a feudal society to a “modern” nation. Emperor Meiji hid an important secret in the box.
- The box can only be opened in the Year of the Dragon (so every twelve years)
- Everyone who has tried to open the box over the years has either died or disappeared
