From the book jacket:
Will Everett has always wished for an adventure. Little does he know his adventure starts the moment he boards the Boundless. There is a murder, and now Will protects a key that can unlock the train's hidden treasures. Villains are fast on his heels and strange creatures are lurking outside the windows, as the Boundless hurtles across the country. Together with Maren, a gifted escape artist, and Mr. Dorian, a circus ringmaster with amazing abilities, Will must save the Boundless before someone else winds up dead.
His adventure may have begun without him knowing... but how it ends is up to Will.
I read this book with my 11-year old son so it took us a long time to finish. We usually read at night before he goes to bed. He really enjoyed this book. I liked it, but it isn't my usual type of book. There was plenty of adventure and edge of your seat moments. Will is a very believable character and his friendship with Maren has its ups and downs. Mr. Dorian seems to be a genuinely good guy who really cares about Will & Maren. His magic tricks are a fun part of the book. The villain, Brogan is a great example of a man with a "perfect" plan that is falling apart because of a young boy. He gets more and more reckless and angry as the book goes on. There are unusual beasts in this book, Sasquatch, Wendigos, the muskeg hag. Good guys, bad guys, magic, circus acts, danger... all of these things really appealed to my son and made this a fun read.
Middle grade readers, boys or girls that like adventure stories.
