Okay, Cupid
(Book)

"As a cupid, Jude thinks they understand love a little bit more than the average human. It makes sense -- Jude's been studying love their whole teen life. And, yes, there have been some bumps in the road, and they're currently on probation for doing something that they absolutely, definitely shouldn't have done... but they're ready to prove they can make matches without ever getting involved. Only... Jude's next assignment isn't about setting up two adults. No, this time Jude has to go to high school, with kids their own age. And the assignment is a tough one: two best friends who are meant to be more than just best friends... but who aren't currently speaking to each other after a huge falling out. Jude thinks they've got this one all under control, and that they won't get involved whatsoever. Which proves that maybe Jude hasn't learned the first lesson of humans and love ... It’s complicated."--,FantasticFiction.com.
