When Katherine Armstrong arranges a birthday weekend on her husband's private island in the Everglades, she plans for everything: the guest list, the menu, the flowers, the careful distance between herself and the dark water beyond the dock.
She does not plan for the storm.
By nightfall, the power is gone, the mainland is unreachable, and something in the mangrove shadows has begun to move. Katherine has spent years building a life that looks flawless from the outside. Now, with her children beside her and the water on every side, she will have to decide what that life was actually worth.
Sixty years earlier, a World War II veteran named Conrad Boone made a decision on these same waters - one that seemed containable, even necessary, at the time. He passed the consequence of that decision to his family. They learned to live with it. And the island learned to keep its secrets.
Until the storm.
The Glades moves between a Florida that no longer exists and a Florida that is drowning in its own inheritance, between a man who thought he could manage what he'd done and a woman who never knew there was anything to manage. What lives beneath the water has been patient for sixty years.
It will not be patient much longer.
