Allisn McKready is a succubus. So is her twin sister. But while Allison spends her summer break hiding in the library behind her Goth makeup, Jade fools around as often as she can. Allison can’t believe Jade would ignore their mother’s fatal example so recklessly, but concealing a cursed bloodline and its dangerous effects is far from Allison’s only problem. Mean girl Julie’s snob mob is determined to ruin her summer, and Aunt Sarah’s Bible thumping is getting louder. Only her new friend, Ren Fisher, offers safe haven from the chaos of her life.

When one of Jade’s risky dates leads to humiliation and sudden tragedy, Allison reels, and Ren catches her. But as her feelings for him grow, so does her fear that she’ll hurt him—or worse—in an unguarded moment. The choice is coming—love him or save him—but Allison might not live to make it. One way or another, the curse will have its due.
