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.
