Bows & Eros by Ava Devlin

Love is in the air …
No, really. Love is literally flying around town, attacking people.
A ten-year-old prankster, one of my favorite students, has sent our entire village into romance-themed chaos, compliments of several dozen paper airplanes whizzing around town and turning anyone who touches them into lovesick fools.
I am the only one who saw it happen, and now the kid that would be Cupid has gone missing. Oh, and the paper airplanes seem to be multiplying.
With an unexpectedly sexy single dad at my side and hints of mythical meddling, my mission to find the boy and stop the madness is underway.
Of course, nothing at all goes as expected.
