Sarah Miller, a gifted archivist whose career and nervous system have been wrecked by three past stalkers, accepts a lucrative live-in commission at Noah Vance’s sealed penthouse tower and learns too late that the contract’s isolation clause is a trap he engineered.

Noah, a control-obsessed billionaire who hears a phantom countdown whenever a variable he can’t secure exists, has bankrupted her, ended her lease, and moved her belongings in order to guarantee she can never leave.

As Sarah maps his cameras and locks with an archivist’s precision, the two negotiate a volatile dynamic in which her explicit, revocable consent becomes the one system he cannot override.

The book turns on whether a man who built a cage can learn that safety proven by removing someone’s choices is not love.

Tropes: billionaire captor, captivity romance, morally black hero, touch-her-and-die obsession, trauma-bonded heroine, forced proximity, damaged heroine competence, enemies-to-lovers power exchange, grovel and restitution arc, she holds the leash reversal
