The Weak Becomes Strong

Madelyn is a white werewolf, a coloring almost nobody is born with, and she was raised by a vampire who took her in as an infant. Growing up outside any pack meant growing up as the thing other young wolves practiced cruelty on, and Hank, who is due to inherit the local Alpha title, made most of that his personal project. Then Madelyn meets Princess Caroline and the bond between them settles as a mate bond, which gives her something to protect and gives Hank something to take away. He seizes her and hauls her back to the pack she was born into, where her father still runs things and where the beatings she was too young to remember start up again. Inside that pack she finds a sister she never knew existed, and the sister fills in what happened the night Madelyn was given away. Knowing it changes how she fights. She stops absorbing what her father and the Alpha do to her and starts answering it, first in small refusals and then openly, until the question of who holds the pack is settled by force in front of everyone who watched her be beaten as a child.
