Her sister died at the Bellgrave Hotel. The hotel swears she was never there.
Forensic accountant Mara Vale enters Bellgrave under false credentials, carrying a brass key engraved with her sister's name. The key opens Room Thirteen, a floor erased from every public plan. Before Mara can reach it, Lucian Bellgrave catches her.
The controlled hotel heir has six days to stop his family from selling Bellgrave and destroying its sealed archives. His offer is simple: become his temporary wife, help him secure the deciding vote, and gain legal access to the room Nora died trying to expose.
Mara expects a contract. She finds a dead bride's dress, payroll accounts that keep paying the deceased, and evidence that someone inside Bellgrave has been preparing for her arrival. Every answer draws Mara and Lucian closer, while each locked door gives their enemy another chance to finish what began with Nora.
To uncover the truth, Mara must decide whether Lucian is her safest ally or the final Bellgrave lie.
The Bride in Room Thirteen is a gothic romantic suspense featuring marriage of convenience, forced proximity, buried family crimes, a guarded heroine, a powerful hotel heir, and a complete romantic ending.
