The Duke’s Daring Bride by Caroline Lee

What is the price of her innocence?
Miss Olivia Wilson is desperate, and desperate women do daring things.

He might not speak, but she can’t deny his dark and dangerous appeal, and there would be worse hardships than becoming a fascinating duke’s plaything.
