A sealed wall. Six stolen names. One marriage Bellgrave prepared before either spouse was born.
When a woman Mara Vale recognizes as her missing mother speaks from behind Bellgrave's chapel wall, she leaves a warning, a brass key, and a covenant signed by women whose identities the estate erased.
One signer is false. One witness has vanished. Mara has been named as the seventh woman without her consent.
To find the missing women, Mara and her husband, Lucian, must enter the House of Wives, follow a hidden passage beneath the estate, and uncover why Bellgrave treated names, marriages, and children as property. Each answer draws them toward the families that shaped them and the arrangement prepared long before they chose each other.
The covenant can expose the truth and remove Bellgrave's private control. It can also turn Lucian's blood into another key and Mara's name into another inheritance.
They survived the hotel by choosing each other. Now they must prove that choice can survive the truth behind the wall.
The Vow Behind the Wall is Book Three in the Bellgrave Vows series, a continuing gothic romantic suspense saga. For the strongest reading experience, begin with The Bride in Room Thirteen.
