Dock And Dominion. Undertow Sins, #37

"The cruelest prisons have no walls. They have open doors and a man who makes you forget you ever wanted to walk through them."After a whistleblower complaint destroys her career, marine biologist Wren Aldridge spends eighteen months fleeing her past on a broken-down sailboat. When her engine dies off the coast of the remote Pacific Northwest, she drifts into Harrow Island's harbor seeking temporary refuge.
There, she meets Stellan Voss, the imposing and fiercely controlling harbor master. From the moment Stellan sees her, he decides she belongs to his harbor. Under the guise of protection and necessity, he builds an invisible cage around Wren. He hides her engine's replacement parts, quietly sabotages her radio antenna, and manipulates the isolated island's ferry captain to cut off her escape. Trapped by the dense, unyielding fog and Stellan's quiet, calculated acts of kindness, Wren becomes entangled in a slow-burn game of obsession and survival.
But Wren is not a woman who breaks easily. When she uncovers the full extent of Stellan's deception, she must face a terrifying truth: she has the power to leave, but the man who built a prison out of care might be exactly what she needs. Dock and Dominion is a dark, gripping psychological romance about isolation, obsession, and a toxic love that refuses to let go.
