Everwinter - The Wrath of the Northmen, #1

Can science and magic ever exist in harmony? Bram, an engineer in the southern city of Ral Tora, doesn't think so. It's science that will save his city from the cruel winter devouring the land, not superstition. But as the ice draws closer and Ral Tora's science fails, his convictions don't seem quite so secure, especially when a stranger arrives claiming that he holds the key to salvation. Astrid, Regal of Chellin, doesn't care.
Ruthless and ambitious, she's climbed over everyone to get where she is - and she's not about to let the Everwinter ruin everything she's worked for. Determined to turn the chaos to her advantage, she needs just one thing to achieve her goal -a certain Ral Toran engineer who is far more than he seems. Falen, banished princess of the northern city of Variss, knows more than she's letting on. Her adopted home of Ral Tora might think magic isn't real, but she knows otherwise.
Tasked by ancient edict to guard a terrible secret, her family has long been aware of the threat imprisoned beyond the Broken Sisters - and the disaster that would unfold if it was ever released. Now the fate of the land lies suddenly in the hands of a manipulative politician who'll stop at nothing to further her own ends, a disgraced princess who is desperate to put right her family's shame, and a sceptical engineer who doesn't believe in any of it. Enter a realm where science and magic collide in the grip of the Everwinter, promising an epic journey through rich landscapes and captivating characters in this first book of The Wrath of the Northmen epic fantasy series.
