Marry In Secret - Anne Gracie

Lady Rose Rutherford has a plan to grant her the freedom she so desperately desires: she will enter into a union of convenience with the biggest prize on the London marriage mart. There's just one problem: the swarthy and fierce-looking man who claims to already be her husband. When Thomas crashes her wedding to the Duke of Everingham, Rose fears for her sanity. The young naval officer she'd fallen in love with and married in secret had disappeared, gone like the ship he was thought to have died on four years ago, and in his place remains a cold, hard stranger with one driving purpose - revenge.
