Killer Instinct — Marilyn Victor; Michael Allan Mallory

As arguments rage across the country over the federal protection status of the gray wolf, an unknown hunter in northern Minnesota declares open season on the disputed animal. After zoologist Lavender "Snake" Jones and her old friend Gina Brown, a wolf biologist, discover four wolf carcasses in the woods near Wolf Lake, Snake is taken aback as an enraged Gina swears vengeance against the shooter. Events take a dark turn when a cantankerous local man with outspoken anti-wolf sentiments is murdered and Snake fears Gina has acted upon her threat. Snake finally comes to grips with the killer in the dark interior of Superior National Forest, where she finds herself in a desperate struggle for her life.
