Dragon's Winter

Born to the shape-shifting dragon king of Ippa, twin brothers Karadur and Tenjiro share an ancestry, but not a bloodline. Only Karadur carries dragon blood, destined to one day become a dragon and rule the kingdom. In an act of jealous betrayal, Tenjiro steals the talisman that would allow Karadur to take his true dragon form and flees to a distant, icy realm. Now, years later, Tenjiro has reappeared as the evil sorcerer Ankoku. His frozen stronghold threatens to destroy Dragon Keep, and Karadur must lead his shape-shifting warriors on a journey to defeat his brother and reclaim his destiny.
