How to Engage an Earl by Kathryn Caskie

The last thing the Earl of MacLaren wants is a wife, so when he awakens to discover a fair-haired enchantress at the foot of his bed, he behaves as any man might by taking full advantage of the delicious situation. Then his family bursts in, and the chit brazenly announces that she is his betrothed. So he finds himself well on his way to being legshackled for life!

Beautiful, reserved Anne Royle had never done anything so mad in her life. She entered the earl's bedchamber with no intention of seduction. Rather, she hoped to discover a document that could contain the truth about her heritage. But now her world is turned upside down, and while she trembles at the thought of her wedding night, she finds she longs for it in ways she never thought possible.
