If I Fall - Kate Noble

After a duke's betrayal, the resilient Sarah Forrester reinvents
herself as society's leading light-the life of the party. It's all a
faade of course. When an old friend returns to London, he's determined
to rediscover the true and trusting Sarah he once knew. But it'll take
more than a kiss and a promise-it might even call for an innocent and
necessary deception.
