Possessive Alpha by Eve Bale

Fated…
For six years, I’ve had one priority. Just one. Keep my sister alive.
Until Ty Logan. One bizarre gas station incident leads us to Dawley, Colorado, and to the fated mate who means to claim me. There’s no escaping his forest-green stare or the way he offers me the things I’ve always secretly wanted.
I’m desperate to stay. My sister is itching to leave. I can only have one priority here. That can’t be Ty. When a threat I barely dodged comes hard and fast for the sister I swore to protect, there’s only one person I trust to help me. Ty.
Do I have a future with Ty, the mate I never saw coming? Or will I lose my beloved sister?
