London, 1817

Sean Delaney has no shortage of female admirers, but all he wants is a divorce—for his sister, that is. Too bad her rotter of a husband, reclusive oil painter John Hamilton, won't consent unless Sean agrees to help him pull off a major deception. With his sister's happiness on the line, Sean has no choice. But he won't be able to do it alone...

Though Lady Corinna Chase is more interested in pursuing her art than finding a husband, she can't help but take notice of the handsome Irishman who's moved in next door. When it soon becomes evident that her new neighbor isn't who he says he is, rather than expose him, she finds herself drawn into the hoax. As collaboration grows into admiration, and temptation breeds desire, Corinna faces a difficult choice: Will she abandon her artistic ambitions, or give up the man she's come to love?

Meanwhile, Corinna's brother Griffin is helping their alluring cousin Rachael find her father. Thank goodness they're cousins, because Rachael has made it clear she won't ever marry one. Except…they discover she isn't actually his cousin. Good God, he's really in trouble now…
