Crazy Rich Aliens (Alienn, Arkansas #6)
Fiona Roarke

In a large, boisterous family responsible for keeping the Alpha colony in Alienn, Arkansas hidden from the humans, Wheeler Grey is known as the brother who stays out of trouble. They have no idea he has a secret life as the artist known as Alias-X, risking exile from Earth if anyone finds out about his clandestine trips to New York City to sell his work. When he encounters a certain dark-haired beauty, he wants her as his muse.
After mistakenly accusing Wheeler of leading her sister astray, Ana is glad to have him to lean on when trouble finds her in Alienn. She’s even happier when he offers to be her guide and accomplice in the hunt for her sister, who may have gone on the run with his brother.
But there is more going on than either of them realized.
And ignorance might get them killed.
