Lillian and Madison were unlikely roommates and yet inseparable friends at their elite boarding school. But then Lillian had to leave the school unexpectedly in the wake of a scandal and they’ve barely spoken since. Until now, when Lillian gets a letter from Madison pleading for her help. Madison’s twin stepkids are moving in with her family and she wants Lillian to be their caretaker. However, there’s a catch: the twins spontaneously combust when they get agitated, flames igniting from their skin in a startling but beautiful way. Lillian is convinced Madison is pulling her leg, but it’s the truth. Thinking of her dead-end life at home, the life that has consistently disappointed her, Lillian figures she has nothing to lose. Over the course of one humid, demanding summer, Lillian and the twins learn to trust each other—and stay cool—while also staying out of the way of Madison’s buttoned-up politician husband. Surprised by her own ingenuity yet unused to the intense feelings of protectiveness she feels for them, Lillian ultimately begins to accept that she needs these strange children as much as they need her—urgently and fiercely. Couldn’t this be the start of the amazing life she’d always hoped for?

Lyla has always believed that life is a game she is destined to win, but her husband, Graham, takes the game to dangerous levels. The wealthy couple invites self-made success stories to live in their guesthouse and then conspires to ruin their lives. After all, there is nothing worse than a bootstrapper. Demi has always felt like the odds were stacked against her. At the end of her rope, she seizes a risky opportunity to take over another person’s life and unwittingly becomes the subject of the upstairs couple’s wicked entertainment. But Demi has been struggling all her life, and she’s not about to go down without a fight. In a twist that neither woman sees coming, the game quickly devolves into chaos and rockets toward an explosive conclusion. Because every good rich person knows: in money and in life, it’s winner take all. Even if you have to leave a few bodies behind.
