Alien Sacrifice by Sadie Carter

Sent to Zerconia as a spy, Annabel is certain she’ll discover some nefarious plot to lure human women to Zerconia. Instead, she encounters a race of honorable, protective, gorgeous Alpha aliens.
Not that she’s attracted to any of them. Nope, not at all. Particularly not arrogant, grouchy, stick-in-the-mud Macon
Macon has his future mapped out. He likes his life well-ordered. His mate will be obedient, honest and most importantly, Zerconian. He does not understand these human females. They are strange, confusing, loud and fragile. Far too fragile.

They are not for him.
No, he will never take a human mate.
Never.
