The Last Signal

When software engineer Maya Chen receives an invitation to an exclusive wellness retreat on Washington's remote Raven Island, she sees it as a lifeline. Facing a devastating lawsuit and desperate to pay for her mother's care, the generous honorarium is too good to refuse. All she has to do is surrender her devices and spend five days "disconnecting." But the Blackwood Wellness Center isn't what it seems. Under the guise of therapeutic confession, the retreat's enigmatic founder, Dr. Sienna Blackwood, is building something far more sinister—a blackmail network that ensnares successful women across every industry. Each confession is recorded, each secret weaponized, each guest transformed into an unwilling puppet. As Maya uncovers the truth, she realizes she's trapped. The house is wired with surveillance. The island is isolated. Previous guests who tried to escape ended up dead, their deaths ruled "accidents." But Dr. Blackwood made one mistake—she brought in a woman who understands systems, codes, and how to break them. With help from an unexpected ally whose daughter was murdered on the island, Maya has one chance to destroy Dr. Blackwood's empire from the inside. But first, she'll have to survive long enough to execute her plan. Some secrets are worth keeping. Others are worth dying for.
