Above the Snowline, the fourth Castle book, is finished and with the publishers. At last!

What's it about? Here's the blurb:

Awian exiles are building a stronghold in the Darkling mountains, where the Rhydanne hunt. Their clash of interests soon leads to bloodshed and Shira Dellin, a Rhydanne huntress, appeals to the immortal Circle for justice. The Emperor sends Jant, half-Rhydanne, half-Awian, and all-confidence, to mediate. As Jant is drawn into the spiralling violence he is shaken into coming to terms with his own heritage and his feelings for the alien, intoxicating Dellin.

It's available for pre-order from Amazon now, although the wheels of publishing grind exceedingly slowly so it might be some time before you receive one...

I'm now starting another book, also in the Fourlands, but with a fresh voice and a new setting.
