Racing the Storm by E.M. Lindsey

My job was simple: provide the voice of reason on the Alpha Council so no one gained more power than anyone else. And it remained that way until the humans managed to fracture our numbers. And worst of all, the only Omega I have ever met to make my heart pound has gone missing.
Danyal is more than just a geneticist dedicated to our cause. He’s also the one Omega I shared a heat with decades ago.
But Danyal doesn’t seem to remember our night, and it’s not something I’m eager to bring up again, but I will never forget the way I wanted him. And now that his life is in danger, it’s all I can do to keep the course and not tear the planet apart. I’m not sure what I expect to find when I finally catch his scent, but I know I’m not leaving until he’s safe in my arms.
