Jodi and Jill Spingold are the Spinster Sisters. With a radio show, speaking engagements, DVDs, and two bestselling books, they've built a thriving cottage industry helping other single women find happiness. Their futures have never been brighter-until Jill turns out the lights on Jodi by announcing her engagement.

Jodi is stunned. How can they be the Spinster Sisters if one of them is married? Complicating things is her own love life, involving three vastly different paramours offering three different kinds of happiness-none of which Jodi is sure she wants. And her ex-husband, backed by his lawyer girlfriend, may be angling for a piece of the Spinster Sisters empire.

Now, Jodi must make some tough decisions, keep the business afloat, and get to the altar to stand by her sister-even if means that from now on she'll be single all by herself.
