Junetta Beale, owner of the Shipshape Bookshop, is happy to welcome her former fiancé and his bridal party to her small Southeast Alaska town. They plan a brief cruise of the Inside Passage on her floating bookmobile, the Northern Dream. She maintains that she no longer harbors romantic feelings toward him.

What could go wrong?

Then a fire breaks out onboard with the captain unconscious at the wheel as the weather takes a turn for the worse. They abandon ship and wash up on a remote island, where Junetta's survival skills using duct tape and blue tarps are put to the test. When morning breaks and a dead body is discovered, Junetta faces a raft of challenges. She realizes that the fate of the wedding lies in her hands. Can she bring the group safely back home over the waves and expose a killer before her submerged feelings for her ex resurface?
