Wolf Keeper by Yumoyori Wilson

Three Chosen Paths. One Destined Future. A Finale Only She Can Face.
After a traumatic accident, amnesiac Harper Blake wakes up in unfamiliar surroundings and being tended to by a stranger — an important stranger she should have met long ago. Her new friend helps provide answers, but as a foreign side of her power awakens, even more questions unfold.
As she’s introduced to new allies and a different way of life, she must face the difficult task of rediscovering who she really is as quickly as possible, for her people are on the brink of war. One thing is clear: she is a leader, and with the help of her mate, she’ll do anything to stop the pack of wolves trying to upset the balance among the supernatural race.
There’s only one small problem: a feeling of hopelessness that Harper has lost something — or someone — vital. She has no idea how to quell the dread inside, but she senses that if she doesn’t hurry and find out where she came from, and more importantly, where she belongs, it may be a problem that can never be fixed.
The final chapters are coming to a close and Harper’s love, power, and desire for unity will be tested. Will she be able to bring peace to the shifters and find out who she is before time runs out?
Or will she lose crucial parts of herself forever?
