'Tender, complex, complicated and passionate: a heady mix that doesn't let up until the final page. Stunning.' VERONICA HENRY.

'So evocative. A great summer read!' GOOD HOUSEKEEPING.

'A story of love and friendship, it's captivating!' HEAT

A love that can't be stopped.

A secret that will change everything... Marriages end with a whisper, not a bang. Not an argument, which is after all about passion, waves crashing on a shore, but with the small pockets of coldness that an argument creates.

It's like islands. They don't sink like Atlantis. They wear away, little by little, until all you've got left is a single rock and a light.

A warning to safer travellers to stay away. The last time Vee left the shores of Unity Island, she thought she'd left forever. But this summer, she's returning with her charming husband, Mike.

Vee's unexpected arrival, this time as one of the wealthy 'summer people', sets the small island community alight with gossip. What's more, her childhood best friend, Sterling, is furious that she's come back - Vee abandoned him when he needed her most. And then Vee meets Rachel, Sterling's wife, and a spark is ignited within her that she can't extinguish.

And as summer turns to autumn, long-buried secrets emerge that will cause a storm greater than any of them could ever have imagined. But when autumn comes, who will sail away with the tide and who will choose to stay behind on the island...?
