His Little Earthling by S. L. Finlay

He’s an alien. She’s a paranormal researcher. It couldn’t be any more perfect that it’s her he has to abduct.
When Jenny is taken from her bed in the middle of the night by little gray men – from a UFO conference of all places – she finds herself delivered into the arms of an unlikely suitor.
He is tall, broad, deadly sexy and purple.
Dr. Jora – or Jack, as he goes by – is as curious about Jenny as she is him, and an unlikely coupling begins to take shape.
But what happens when they return to Jack’s home planet and Jenny is forced to question everything she thought she knew about humanity and herself? Will Jack step up and be the strong man she needs, or will he slink away in search of greener pastures?
