At twenty-nine, Alison Marshall is ready to find a place to call home. With no family and no ties, she's drifted from one small Florida town to another since high school, working odd jobs, saving hard, and building a nest egg. Once she finds the right place to settle down, she'll know. And when she reaches beautiful Palmetto Island, she thinks she may have found it.

The small, close-knit island community seems to have everything Alison needs. On a hunch, she contacts the island's only realtor, and learns that an old beach house is on the market. Miraculously, it's in her budget, and Alison takes it as another sign that she's in the right place.

At first, home is everything she hoped it would be. But as days turn into weeks, she uncovers a dark side to this supposedly peaceful haven. The locals have a secret, and once Alison discovers what it is, she faces a stark choice. She can stay and join them-- or escape. But leaving brings its own risks, and Alison is starting to wonder if coming to Palmetto Island is the last mistake she'll ever make...
