Everwinter by Elizabeth Baxter

Can science and magic ever exist in harmony?

The powers of old and new are on a collision course in the land of Thanderley. Ancient gods have broken free of their imprisonment and cursed the lands with a terrible winter, a scourge that is sweeping science and the new ways from the earth. In the city of Ral Tora, Bramwell, a young engineer, battles to save his home from the encroaching ice. But there will be no exceptions. The gods will reclaim what was theirs and destroy any who oppose them.

Once more, the balances are tipped. Magic and science cannot exist in peace, yet Bramwell must master both to save everything he loves from destruction.
