I'm Not Myself. by Sarah Dunn

Holly Frick just went through the worst kind of divorce: the one where you're still in love with the person divorcing you. Facing up to life on her own, she needs a distraction to keep her mind off her own non-existent love life. Like Jane Austen's Emma Woodhouse, Holly is intimately involved in the lives of those closest to her, and now she feels compelled to give advice with unwavering moral certainty. And, like Emma, she is often completely off the mark. Soon she's in over her head, advising her ex-boyfriend's new girlfriend while at the same time falling for her married friend's new lover. Until, happiness arrives from a very unexpected source ...With a contemporary twist on Woody Allen's Manhattan, Secrets to Happiness is a hilarious look at the things people will do to be happy.
