Indiana by Tasha Black

She needs to get this gorgeous alien undercover.
And all he wants is to get her under the covers.

Nikki Fortune has a secret. Her friends think she’s at Maxwell’s Family Resort to teach drama and take endless tennis lessons. But her real purpose forces her to dig deeper into the network that runs the resort than she ever imagined. If only the distractingly handsome alien, Indiana, weren’t there she might be able to keep her eye on the ball.
Indiana has a lot on his mind, not the least of which is figuring out Nikki Fortune. Why does she disappear every Sunday morning? What’s on that laptop she always carries? Why would someone who obviously hates tennis keep taking lessons? And why, gods, why, is she so blindingly stunningly, achingly sexy?

When Indy stumbles onto some answers the two realize they must work together if they want to uncover the truth. But the only way to do that is to trust each other.

And someone still has a secret.
