Varg by Luna Hunter

Life onboard a spaceship isn’t so bad for Julie Skye — except for the gorgeous and obsessive alien warrior who claims they are fated mates.
His name is Varg.
He is an eight foot tall Dragan warrior with an arrogant smirk and steely buns to die for. He believes — falsely — that he is the Old God’s gift to the human race. Out of all the mateable women on-board the Ravenous, he has chosen Julie Skye from Engineering.
Varg has chosen poorly.
If there’s one thing Julie doesn’t tolerate it’s arrogant men, and they don’t come any cockier than Varg. Despite her best efforts to rebuff him, the Dragan warrior simply will not give up.
Varg promises that eventually Julie will come to see that they are fated mates.
Julie thinks the sun will burn out before that happens.
