From the publisher:
Ever looked out your window and wondered if there was intelligent life out there? Well, don't bother. Trust us.
What IS out there is a crazed maniac who likes to dress up as fruit and furry animals, two evil little faeries who like their humans filleted, a race of polite but conquering aliens led by a suave villain of etiquette, and last but not least, a whiny rich brat who really knows how to annoy masses at large.
Only one force can stop them! The Musical Mistresses!
The Musical Mistresses are a group of young girls who combat evil with musical instruments and magic (along with tempers the length of a toenail). There's Miyoko (supposedly the leader, believed to be a klutz), Akemi (technically a girl, really a psycho), and Fujiko (the one true worshipper of Biff and Yougi - Bishounen carriers of our planet).
They're all we got, and they've got their hands full!
