Finding something that would fit the description of the "perfect diamond" would seem a fool's errand, and Trixie is most definitely a fool. But, she's a fool with a drive, a fool who won't stop until she gets what she wants, a fool in love.

This is the story of Trixie, a trio of irratible bipedal canines, and their quest to find the single most perfect diamond in all of Equestria.
