A Navy neurologist is pulled from her routine caseload to evaluate a single patient in a facility that doesn't appear on any map she's ever accessed.No diagnosis. No history. No explanation — just a security clearance she didn't know she held and a schedule that's already been rearranged without her consent.What she finds in that room changes everything.Dr. Maren Leath has spent fifteen years reading damaged brains. She knows what broken looks like — and what's sitting across the table from her isn't broken. It's something her training never prepared her for, and the answers lead somewhere far more dangerous than the classified walls around her.Untethered is a white-knuckle military thriller with the neuroscience to back up every page — a story of duty, deception, and the question of what remains when everything that makes us human is removed.
