HAPPILY-EVER-AFTER
London socialite Amelia-Rose Baxter is nobody’s fool. Her parents may want her to catch a title, but she will never change who she is for the promise of marriage. Her husband will be a man who can appreciate her sharp mind as well as her body. A sophisticated man who loves life in London. A man who considers her his equal—and won’t try to tame her wild heart…

There is only one way to find out…
