Seventeen-year-old Lydia Cornwallis has arrived on a remote island populated only by wealthy families and their staff. She quickly finds acceptance, even adoration, from the close-knit families that rule the island. But a storm is coming, and all routes to the mainland are cut off.

But thank goodness the Harrington sisters made it in time, because Lydia simply can't wait to meet them.

That's because Lydia's not really Lydia Cornwallis.

And the Harringtons have hell to pay for what they've done.

Lydia will need to draw on epic nerve, quicksilver adaptability and sly cunning in maintaining her cover and exacting murderous revenge. And when she meets someone new on the island and starts to develop real feelings, can that connection survive when nothing else is real?
