Storm Stunner is a pegasus with aspirations to join the Royal Guard: the noble ponies responsible for maintaining the peace and prosperity of Equestria. At least, that's what it says on the cover.

Follow his journey as he joins their gilded ranks, and learns just what life is really like as one of Equestria's finest.

Bon Bon's voice is funny, and that's about all that anypony who meets her notices, as her marefriend Lyra soon steals the spotlight with her explosive personality, strange obsessions, and curious beliefs. And why not? Bon Bon is, after all, a perfectly ordinary, boring pony in every way but two: her voice, and the carefully kept secret that she isn't really a pony.

Ponyville has a problem: Twilight's friends all switched Cutie Marks, and the musical numbers are flying thick and fast.
Lyra has a problem: She can't handle the way musical numbers get into your head and take you over.
Bon Bon has a problem with that.
