Etched in Honor by Carrie Ann Ryan

I thought I’d lost my fated mate until he shows up years later. Only with no memory of me. Or us. As Beta of the Aspen Pack, I was forced to watch our former Alpha turn to dark magic and destroy the bonds of our people. I nearly died trying to save us, but I broke the biggest taboo: I told the others that cat shifters existed and almost lost everything in return. Now we have a new Alpha, a new future, and a dangerous and mysterious enemy threatening our stable balance. And a new Tracker. The man who looks like my dead mate.
