Howl of the Sequoia by Deidre Huesmann

Devastated by her mother's terminal diagnosis, Rachael struggles with day to day existence as her family's cheerful facade splits stitch by stitch. Amidst her crumbling home life, she manages to make few new friends. One in particular, Holden, makes her question if she can even consider love while her mother's life hangs in the balance.

But Aaron Moreno, a lycan alpha, has a another idea: he wants to introduce Rachael to his and Holden's secret lives. And if what Holden says is true, Aaron will have no regard for what havoc this will wreak upon Rachael.
