His Hand-Me-Down Countess (Lustful Lords, Book 1)

Theodora Lawton has no need of a husband. Unfortunately, her father signed her life away in a marriage contract to the future Earl of Stonemere. But then the cad upped and died, leaving her fate in the hands of his brother, one of the renowned Lustful Lords.
Achilles Denton, the Earl of Stonemere, is deeply scarred by his last tour of duty. Balanced on the edge of madness, he finds respite by keeping a tight rein on his life, both in and out of the bedroom. But his brother’s death has left him with responsibilities he never wanted and isn’t prepared to handle including an unwanted fiancée who comes with his equally unwanted title.
Saddled with a hand-me-down countess, he soon discovers the woman is a force unto herself. The question is, can he stay alive long enough to figure out who’s trying to kill him while he tries to tame his headstrong wife?
