Strange Love by Ann Aguirre
We have seen stories where love crosses boundaries, such as time, but in some cases, such as this, it can even cross galaxies. This book follows the mission of matchmaking for Zylar, an awkward alien who needs a nest guardian, as he has a four-game losing streak. If he fails to find one this time, he may be destined never to have a mate at all. He then meets Beryl Bowman, a daycare worker from St. Louis who definitely did not have alien abduction on her bucket list.

Due to some cosmic mistake, Zylar ends up with her instead of his intended mate. Their vastly different personalities and circumstances bring up many misunderstandings, but among those is a budding, unexpected romance.
