The Duchess and the Beast by Claire Devon

A Beast hidden by a mask. A Beauty scorned for her past. A Marriage that is doomed to fail…

Lady Virtue’s reputation shattered the day her ex-betrothed abandoned her at the altar. Scandalized by lies of infidelity, her prospects darken—until her father shocks the ton by promising her hand to the Beastly Duke…
Duke Sebastian is the Beast of Greystone. Scarred by war and masked in white, he struggles with his temper and a shadowed past. With his wealth waning, he urgently needs a quiet bride, and Lady Virtue, equally tarnished by gossip, seems the perfect candidate…
Except Virtue dreams of making a fairytale prince out of this beast yet, even if his anger and self-loathing keep him at arm’s length.
Until a sinister threat seeks to unravel their marriage. And Sebastian is forced to unleash the beast of his past to protect his wife, or forfeit his only chance of happiness…
