The Burdens of a Bachelor: Arrangements, Book 5 (Unabridged‪)‬

What the eye cannot see...

Colin Gerrard has everything. He is a handsome, charming, and unattached gentleman in possession of a fortune. What nobody knows, and would never suspect, is that he is not nearly as carefree as he seems, nor is his heart free for anyone’s taking. It was already taken long ago, and when his lost love unexpectedly reappears, in London of all places, he’s very much afraid she still has it.

...the heart already knows.

Lady Susannah Hawkins-Dean had no intention of ever seeing Colin again after their terrible departure 16 years ago. She never wanted to see anyone who knew her in the past. There were too many secrets, too much shame, and he, of all people, could not know them. But when Colin refuses to leave her in the past, Susannah finds she is just as in love with him as she ever was, and it could ruin them both.
