Alien Healer by Sadie Carter

Racar is determined to find a way to ensure that human females live as long as their Zerconian mates. Solving this problem has become the focus of his life. To the point that he hasn’t even noticed his own mate is right under his nose…
Trying her best to be noticed.
Ellie has tried everything she can to get the clueless, hunky healer to actually see her. Short of running around naked screaming his name she wasn’t sure what else she could do.
And frankly, she wasn’t even sure that would work.
When Racar discovers she is his mate, she doesn’t know whether to trust in him. To believe him.
To let herself hope.
