Fated to the Alien Dad by Erin Hale

Zalik
I have watched as each of my tribe brothers found their human keeshlas, leaving me as one of the last still unmated. Until everything changes. Not only do I stumble across a human kit, but a single touch reveals my fated mate. In that moment, I know my path has been chosen. I will be the one to protect and care for them both.
No one will take my mate or kit from me, not even a powerful male who arrives from Earth.

The past always has a way of catching up with us. When mine does, I seek out the protection of the Tavikhi people. It comes in the form of a warrior who claims I’m his mate. The same one who found my adopted daughter after I’d hidden her deep in the forest when I discovered her life is in danger.
In order to have a future with them, I’ll need to place all my trust in Zalik. But trust is hard when nearly everyone in my life has either left or disappointed me.
