One small favor. One impossible price.

Sunday Reese is broke, hunted by a loan shark, and out of options. So when a car crash on a dark road leaves her stranded in a hospital far from anywhere she knows, it's just one more stroke of bad luck.

Then Bec, the owner of a nearby lakeside lodge, offers her a place to recover. And a way out of the debts chasing her. All Sunday has to do is one thing for Bec first…

But there are things Bec doesn’t know about Sunday. Things Sunday can’t run from forever.

When a woman turns up dead on the lodge grounds, a detective starts asking questions neither of them can afford to answer. Bec thinks she’s in control. Sunday has survived worse than her. Only one of them is right. And in this game, the losers end up dead.

For readers of Mary Kubica’s It's Not Her and Lisa Jewell’s The Family Upstairs, a twisty, emotional and claustrophobic story of how far love should go, an isolated lodge that turns deadly, and a debt that costs far more than money.
