Eli and Max both have good reasons to go to the lighthouse on Shackles Island. For Max, it's an old vacation spot, the rare location where she has only good memories—so it's the right place to scatter her dad's ashes. For Eli, it's the highest point near his Louisiana home, with the clearest view of the rocks where his sister died—so it's the right place to end his own life as well.

But neither of them expected the other…or the storm. Because Hurricane Celeste is roaring toward Shackles Island, and its power will break bridges, slash electric lines, and stir up deadly wildlife—some of it human. When the ruthless Odenkirk family steals Max's Jeep with her most precious possession inside, she and Eli begin a desperate quest to get it back and to get off the island…until they realize they must go into the hurricane to survive.
