Vigloo

When Celeste Voss comes to collect her parents' debt, Nora offers herself in her sister's place — collared, kneeling, and owned. She schemes with a childhood friend to bring Celeste down, even as every touch pulls her deeper. But the collar is a leash, the friend is the trafficker, and Celeste is an undercover agent. To free forty women, Nora must risk the one thing she never meant to give.
