The Fortress in the Frost - The Triple Realm Duology, #2

It is the final years of the 18th century, but a world which few would recognise.  The people of Europe shelter in small islands of safety, havens from the enchanted wilderness - the strange boundless forests people call the Tumble. It is across this demon-haunted landscape that the low-born officer Taliesin must lead his men, caught up in the deadliest of intrigues while fighting wars for a noble class which despises him.
With vicious murderers from the worst gutters in the Realm marching behind him, and the forces of the most powerful nations of the mainland arrayed against him, the odds are stacked against Taliesin. Heavily. Yet he will fight on, battling armies, sorcerers, assassins, beastmen and cross into the face of hell itself. Not for loyalty, or grudging respect for his scheming monarch - not even for the small mountain of silver the Island Queen has promised him if he succeeds.
But because fighting is all he and his pressed band of cut-throats and thieves have ever known. >>>> ABOUT THE AUTHOR  Stephen Hunt is the creator of the much-loved 'Far-called' fantasy series (Gollancz/Hachette), as well as the 'Jackelian' series, published across the world via HarperCollins alongside their other best-selling fantasy authors, George R.
