His Little Emerald by Paige Michaels

Julia is about to learn what it means to have a Papi of her own.

Attending Club Zoom as her roommate’s wingman, Julia has no interest in meeting an Eleadian mate. As required, however, she signs the paperwork alerting her to the risk of an undeniable connection.
Kelkef hasn’t descended to the main floor of the club since his arrival on Earth. Preferring to watch the human females from monitors, Julia is the first female to catch his attention. And she does far more than turn his head.
After realizing his mate has no desire to return to his planet with him, he reluctantly lets her go. He can only hope the tiny prick to her skin wasn’t enough to solidify his claiming.
Unable to resist the lure, it takes less than a week for Julia to return to her mate. She has no idea what she’s committing to, but she will soon learn how seriously Eleadian men take their role as caregivers.
