I have posted a map of Arvanor to the Ferrian's Winter main page, with a few caveats. :)
It's a very old map. I mean, reeeeally old. I drew it when I first started writing the book, so around fifteen/sixteen years ago?? Some of the place names and other details on the map that aren't mentioned in the story are liable to change and/or be completely hypothetical. There are also many important locations that are not on the map at all. (The Sorcerer's Valley is the subtitle of my book!!)
The world of Arvanor has very much grown organically from writing the story. Places arise where needed, around the characters. I'm not a planner. I didn't spend many years worldbuilding in great detail like some other authors do; this map was only ever meant to give a general impression of where things are in relation to other things. So yeah. It's not super accurate, and best used as a sort of overview of the world.
Personally, I don't believe a map is necessary to understand or appreciate the world of Ferrian's Winter (or any fantasy book for that matter!); I trust my readers have wonderful imaginations and are capable of constructing their own mental picture (and prefer them to!) but I realise a lot of fantasy readers really like maps, so... here is one. Enjoy. :)
(Incidentally, when I had it on Deviantart for a few years, this was the most favourited picture in my gallery. From people who'd never even read the story. That's something I find interesting...)
