Duke of Lust by Olivia T. Bennet

“I will never touch you, love. But if you want me to cease my ways, your nights shall belong to me…”

Duke Frederick may be an insatiable rake but he never goes back on his word. So when his friend’s younger sister is left in his care, he vows to protect her. Only, the sweet minx stirs a dark obsession within him…
Nothing must stop Annabelle from finding a match this Season. Not her shy, wallflower nature. And especially not her dangerous protector. Until she steps into his bedroom…and sees something she never should have.
So, Frederick makes her an offer she cannot resist: he shall help her find a husband and she agrees to give him her nights…Yet he must never touch an innocent like Annabelle. No matter how much he yearns to corrupt her.

*If you like a realistic yet steamy depiction of the Regency and Victorian era, then Duke of Lust is the novel for you.
