Vonn by Callie Rhodes

Stacy may be a loyal beta soldier, but she soon discovers that in the wilds of the Boundarylands the only real battle is between predator and prey.
No woman willingly travels to the Boundarylands.
It’s where they are—the Alphas.
They keep to themselves in the wilderness, and beta civilization knows to keep its distance. Especially beta women…for fear they may not be a beta after all.
In the beta army, female soldiers are few and far between, and ones as skilled and highly trained as Stacy Clarke are even rarer. She’s the best of the best. That’s why she’d been chosen for the most dangerous mission—to test a revolutionary omega suppressant in the field.
If she’s successful, many in the beta world will be freed from their greatest fear…but if she fails, she’ll be plunged into a never-ending nightmare.

Welcome to the Boundarylands. A place where the only way to know your true nature is to feel the touch of an Alpha. Omegas may be rare, but every woman knows their fates are hellish—held captive, broken, mated, knotted, and bred.
Vonn is the fourteenth book in The Boundaryland Omegaverse, a hot new ABO romance series featuring knotting, heats, and possession. Wear gloves, cause this sh*t is hot.
