The Last Portage

Commercial thriller

They erased the files. The water kept the evidence.

When aquatic biologist Mark Jensen is found dead beside a silent wilderness lake, one critical piece of equipment is missing: his field laptop.

The rest of his gear is untouched.

A recovered drive contains dozens of empty folders and one name that appears again and again: Sample 14.

Hydrologist Ethan Voss follows the erased evidence into abandoned mine workings, forgotten monitoring stations, and a route called Line Seven, a groundwater pathway official records insist does not exist. The deeper Ethan Voss digs, the clearer the pattern becomes. Scientists disappeared. Witnesses were silenced. Entire decades of environmental data were deliberately removed.

Now a new mining project promises jobs and stability to Northern Minnesota communities fighting to survive. But beneath the granite, hidden water is moving toward protected wilderness, carrying evidence that could destroy the project and expose a conspiracy four decades in the making.

To prove what Mark Jensen discovered, Ethan Voss must trust the one witness no one has been able to intimidate, manipulate, or erase.

The water itself.

Line Seven is an atmospheric environmental conspiracy thriller about murder, buried evidence, community survival, and the terrible cost of choosing certainty over truth.
