Stephanie Perkins is the reason we write romance. Overdue is the book her readers have been waiting for. -Christina Lauren, New York Times bestselling author of The Paradise Problem

Ingrid Dahl is a cheerful, twenty-nine-year-old librarian living in the cosy mountain town of Ridgetop. She and her boyfriend since college, Cory, have never discussed marriage; theyre perfectly happy with the way things are. But when Ingrids sister announces her engagement to a woman shes only been dating for two years, Ingrid and Cory suddenly feel pressured to start thinking about the inevitable: marriage and kids.

The thing is, neither of them has ever been with anyone else. Shouldnt they sow their oats before settling down?

They make the unorthodox decision to separate for a month to date other people, assuming that at the end of it, theyll reunite and start planning their nuptials. And Ingrid has the perfect man in mind for this relationship sabbatical--Macon Nowakowski, her cantankerous and completely adorable coworker for whom shes had a crush for years.

But of course the best laid plans often go awry, and when Ingrid and Cory meet at the end of the month to resume next steps in their relationship, its clear neither of them is ready to get back together...

Overdue is a beautifully human love story - my favorite Stephanie Perkins book yet. - Rainbow Rowell, No. 1 New York Times bestselling author of Slow Dance
