Meet Chase, a boy who conquered his fear of deep water while exploring shipwrecks on Lake Superior with a new friend he met at the museum, Bri. Bri, short for Brizo, is a girl with incredible knowledge about the wrecks, storms, and heroes of the Great Lakes.

Using a magical map, the two begin an adventure that allows them to time travel back to the day of some of the most horrific wrecks in Lake Michigan's history.

With Bri's guidance, Chase experiences the harrowing details of each of the ship's final hours. How did the ship sink? Why did it sink? Was it wrecked due to a storm, fire, ice, collisions, faulty materials, or human error?
