Red, Green, Blue and Wolfen by Hans Erdman

 This is a short story, primarily introducing Tessa Chart the mapmaker.

This is set in the same world as The Gewellyn Chronicles, and so some of the types of beings and interactions are familiar.  However, having only read the first two of the series, some of the givens in this book have almost been spoilers, as in my frame of reference, some things haven't happened yet.

The blurb says:

Tessa Chart, the Mapmaker, has long, beautiful red hair. So does Abilynn, High Princess of the Elves.
When Wolfen, super-werewolves attack the Fairy Circles, the Blue Fairies turn to the Princess for help. But when they mistake the mapmaker for the princess who was raised by the Wolf King, Cormac Mac Art, it could spell doom for the Blue Fae.
They risk ire of the Leprechaun Queen Fillian who rules over the green and blue wee folk alike. It will take a headlong dash across Ireland in Abilynn’s Stutz Bearcat and a Rolling Royce (or something like that), with help from a Drow elf, an assassin-turned-spy, and the Wolf King himself, if they hope to turn the tide and send the Wolfen back where they belong.
Then there is the ever-watchful eye of Fiona, the High Queen of the Magical Folk of Ireland and the Aerielands, the most powerful elf in the entire Nine Worlds, and Princess Abilynn’s mother.
What’s a Princess to do?

This is a very short book (only 39 pages according to Amazon) so it does move at a fast pace.  My preference would be for it to be slightly longer, so we can delve in the world more fully.

For anyone contemplating reading this book, I would recommend that you read the others in the series/world first.
