They were best friends. Sisters of the heart. Partners in crime. Until they got caught ...

Five years ago, Frannie Willets committed grand larceny to help her best friend, Lexi Maddox, escape an awful situation. Now paroled and prospectless, Frannie needs to disappear from her dead-end life. To do so, she'll need her share of the stolen money that Lexi has been hiding all these years. But Lexi has other plans.

By all appearances, Lexi is thriving, but in truth, nothing in her life is going according to plan. She can't carry a pregnancy to term, her sweet stepdaughter hates her, and even the family's new rescue dog knows she's a failure. Lexi's only path to happiness is making amends with the friend she dearly misses. But the only thing Frannie wants from Lexi is cash.

Out of desperation, Lexi offers Frannie all the money, with one catch: Frannie must stick around for one month. Stranded in their suffocating small town, Frannie gets tangled up in Lexi's issues, her mother's questionable dating life, a lonely kid's desperate attempts to find friends, and a high-school crush's fantasies about what could have been. Suddenly, leaving doesn't look as easy as it once did. But when an old enemy surfaces, Frannie realizes her staying endangers everyone she loves. And even though she might have found her heart's true home, there's no guarantee she can keep it.
