Can cold water heal broken hearts?

12 months.
162 cold water swims.
1 missing woman.

We call ourselves the Tragic Wives’ Swimming Group, well, because . . . we’ve all had something bad happen to us.

The man I thought I was going to marry did the unspeakable with a cute young florist. Not long after, my sister drowned on a family trip. Now I’m at my ex’s beach house in Cape Cod, hoping to get past my heartache and figure out what to do next with my life.

Three mornings a week our swimming group meet at sunrise and plunge into the ice-cold depths of the Atlantic.

But then we find out that Rachael, the one who’s always late, has written a tell-all book exposing our darkest secrets. Word spreads that she’s uncovered something so juicy — so twisty and unexpected — the book will be a bestseller.

A few days later, Rachael disappears . . . leaving just a pile of clothes on the sand.
