Have we been missing out again?

Operating on a reader recommendation, I've put in a request for the 2005 Tor reprints of Michael de Larrabeitti's Borribles trilogy (originally published between 1978 and 1986). This is yet another fantasy trilogy that I've never heard of, and according to its Wikipedia entry it sounds like another series with just one female main character, but I must say: the Tor reprint covers really speak to me. They're like those animated Christmas specials from the 'seventies... only, y'know, evil-looking.
