Come Alone To Floor Thirty-One. Nightlock Sins, #8

"The cruelest prisons have the softest beds. Ask any woman who stayed-not because the door was locked, but because the man who held the key had already memorized every room she'd ever want to leave."Simone Avery is the best forensic litigation attorney in Nevada, a woman who spent four years rebuilding her life after fabricated evidence destroyed her career. She trusts no one, relies only on facts, and never lets her guard down.
But when an anonymous envelope containing explosive evidence of a corporate money-laundering scheme arrives inside her locked apartment, it comes with a simple instruction: Come alone to floor thirty-one. Garran Merrick is the enigmatic CEO of a multibillion-dollar real estate empire. He is also currently handcuffed to his own desk on a secret, locked-down floor of his flagship skyscraper-the victim of a hostile corporate coup.
To reclaim his company and expose the men who ruined Simone's past, he needs the one attorney capable of untangling a decade of financial fraud. He needs Simone. Trapped together in a high-tech bunker while his enemies search the building below, Simone and Garran must build the legal case of their lives. But as she sifts through the evidence, Simone makes a terrifying discovery: her arrival was no accident.
Garran has spent months obsessively studying her every habit, curating a workspace-and a living space-designed specifically for her. He didn't just need an attorney. He needed her. And he built a cage disguised as a shelter to make sure she stayed.
