Six people. One portable radio. A coast that will not make anything simple.

When the forecast turns, the supply vessel Morrow does what a careful crew should do: she goes back. But the harbour she turns back to is closed, the anchorage she chooses is not as safe as it looked, and Arden Vale, travelling as the ship's logistics contractor, soon learns that every decision aboard is a trade between two risks.

Arden once coordinated rescues from the safe end of a radio. Now she is on the wrong end of one. Sera Voss is the skipper, with a ship to answer for. Ivo Calder is a technician who can repair a great deal and cannot build what he does not have. Petra Lennox knows how far a pantry will stretch. Bram Rusk is the youngest deckhand, with more to learn than the sea will allow time for. Lio Serrat brings medical experience to the voyage. And on a bare island, a caretaker named Emil Tern keeps a shore camp, a stove and a few tins of food.

The mainland has heard part of their call. The station they were bound for has six people of its own and a tower that needs parts the ship was carrying. Nobody has the full picture, and the people who could help are very far away.

Where the White Sea Ends is a survival novel about skill, limits and the stubborn work of keeping each other alive. It is also about the records, the costs and the decisions that reach beyond a single voyage.
