"The first wretched pangs of teenage love are hard enough --- but what if the object of your affection was standing right in front of you, and yet completely unobtainable? Like, utterly, totally, out-of-the-question unobtainable? For 15-year-old Amelia, such struggles are the stuff of everyday life, especially when she works just a register away from the most desirable man on earth…or at least, the most desirable in her eyes."
Copied from back of book. In other words, romance with a teenager and her coworker.
