Review

This was a very good book. I really liked how you had to try and figure some things. The code was very unique and hard to figure out. It was also cool. It was also cool that at the beginning it tells you about Pentominos, so you could figure out what they were and understand the book. Tommy was my favorite character because I liked how he collected a lot of things. I also liked that Calder used his Pentominos to figure out things. I would definitely recommend this book to people who like mystery and suspense.
