The Unnatural Quarter becomes a grim fairy tale in Dan Shamble's most pointed case.

When the Big Uneasy returned all monsters and mythical beasties to the world, something was missing. After his vampire girl Alvina flunks a school report on unicorns, Dan is embroiled in a deeper mystery: With unnatural creatures on every streetcorner, why has no one ever seen a unicorn?

But other weird clients demand the attention of a zombie P.I.-a lovestruck frog demon just wants her handsome, befuddled prince back after an evil spell wears off.

A fairy godmother entrepreneur and her pegasus partner launch a line of glass footwear, but they find that it's a fragile market.

Hard-working lagoon creatures struggle with trespassers, vandals, and civic ordnances as they launch a new swampy resort and spa.

A gambling-addict dragon needs a special support animal, and the local Bigfeet just want to be seen for who they are.

These cases lead Dan Shamble and his companions to a secret society of Horn Brothers, where unicorns are murdered, where evil wizards are just trying to make amends, where fairy godmothers are not what they seem, and where the unicorns' magical pets-their beloved horn dogs-are being dog-napped by a mysterious force.

And the undead just want a Happily Ever After, like everyone else.
