They've been best friends since seventh grade. But this summer, teetering on the threshold of thirty, four women are going to need each other more than ever

Cassie has sworn off men after yet another bad date though, deep down, she's still looking for Mr. Right. A long-haired, tattooed biker is definitely not him, so there's no harm in a few Harley rides through Sonoma. Right?

Julie married her high school sweetheart too young and now wonders how her life became all about leaky faucets and checkbook balances. Maybe love isn't enough to sustain the perfect couple.

Marty's firefighter husband takes her for granted, and with her marriage on the rocks, an old flame begins to look mighty tempting. She's seriously thinking of crossing that line.

Beth is a busy doctor trapped in a body that's betrayed her yet again and she's becoming a difficult patient and a secretive friend. She's fighting for her life.

Life can change in an instant...or a summer. As these four friends deal with life's challenges, the strength of their bond will see them through.

No one delves into the complexities of female friendship better than #1 New York Times bestselling author Robyn Carr.
