Amber Silverblood by Adam Bolander

Meet Amber, a teenage girl struggling with the death of her father, an overstressed mother- and lycanthropy. Amber wants nothing more than for things to go back to normal, but a magical corporation has its sights set on her. Six months ago they lost a very important test subject, and they think Amber will be a suitable replacement. If she refuses to go with them, a demonic crime lord has his own plans for her as well. Stuck between a rock and a hard place, Amber is forced to find allies in the midst of her enemies while still trying to keep her new wolf-ish nature under control. Only one thing is certain: she can trust nobody but herself.
