In life's stormy waters, it's your friends who keep you afloat... Maddy Wolfe's life has just capsized. After her twenty-year marriage suddenly implodes, she heads to Brighton to search for her estranged son, Jamie. But he's nowhere to be found and for the first time, she's totally alone. That is, until she meets the Salty Sea-Gals, a group of feisty sea-swimmers. Seventy-two-year old Helga is determined not to slow down, while thirty-something Tor is still figuring out who she is. Bereaved Dominica is trying to find a reason to carry on, and busy mum Claire is learning to put herself first for a change. As their regular cold-water plunges become a lifeline for them all, Maddy starts to realise that these brave women might just help her find both Jamie and herself. Together, will they turn the tide?
