It's a fairly detailed but not exhaustive map. I've not included every single road and river, but enough to give a feel for the place. Some cities have already been mentioned (most obviously, Falchester, but also Penmere and Caer Seren) but most are entirely new. I've gone for a realistic naming approach so I imagine there are lots of places that have the same name in real life, but this is coincidental rather than deliberate.
The Welsh, for which I'm indebted to Tomas Forsey for his assistance, is used for Arthenigan, in the north. Note that Tomas suggested using Arthenigion (as per Ceredigion, I think) but I preferred the sound of Arthenigan. It also fit an English (or Dennish) dominance, as does the real-world Cardigan.
Various place names have lore influences, prefixes from the names of the gods, for example. I'm also indebted to Michael Kaye for his help making the coastlines rather more realistic.
The story itself revolves around the civil war between (and tempestuous relationships within) the Houses of Penmere and Esden. It's brimming with ruthless she-wolves, scheming traitors and grim knights. Amazon doesn't allow pre-order reviews but a few early ones are up on Goodreads.
