About Last Night by Ruthie Knox

Cath Talarico knows a mistake when she makes it, and God knows she’s made her share. So many, in fact, that this Chicago girl knows London is her last, best shot at starting over. But bad habits are hard to break, and soon Cath finds herself back where she has vowed never to go . . . in the bed of a man who is all kinds of wrong: too rich, too classy, too uptight for a free-spirited troublemaker like her.
Nev Chamberlain feels trapped and miserable in his family’s banking empire. But beneath his pinstripes is an artist and bohemian struggling to break free and lose control. Mary Catherine–even her name turns him on–with her tattoos, her secrets, and her gamine, sex-starved body, unleashes all kinds of fantasies.

When blue blood mixes with bad blood, can a couple that is definitely wrong for each other ever be perfectly right? And with a little luck and a lot of love, can they make last night last a lifetime?
