A Deal with the Wicked Duke by Harriet Caves

“I have been starving for you, Caroline. Dreaming of this. Let me worship you the way you deserve.”

Yearning for adventure before she’s married off, Lady Caroline devises a list of forbidden escapades. But the moment she tackles the first, she crashes into her brother’s wickedly handsome best friend.
Rake to the marrow, Duke Anthony steers clear of innocent ladies. Until he catches Caroline sneaking through London’s darkest corners… and learns exactly what she’s planned.
To protect her, he sets one rule: she may finish her list, but only with him. Yet when the final item demands a kiss, Anthony must resist… for she is the one woman he must never touch.

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