Love Before Dawn by Claire Cullen

When Jethro’s Alpha mark lights up, he knows that somewhere out in the world, his Omega has come online. It means everything to him as the last Alpha Prime; true love, happiness, and the power to form a clan. If only he can find him.
But his Omega, Miles, is south of the border, in a place where he’ll be conscripted to serve the needs of their military’s Alphas. If that happens, he’ll never be Jethro’s. To make matters worse, Miles is the South’s latest poster boy for Omega recruitment, painted as a true believer in the system that will bind him in virtual slavery.
Jethro’s choice is clear; give up on a true bond and the happiness, love, and children that come with it, or go south to steal the Omega who should be his. But Jethro can’t just steal him away, he must win over Miles’ heart and convince him that they’re meant to be, all before the authorities catch up with them and Miles is lost forever.
