The Dragon Emperor: The Chronicles of Kylen Ly'selle

Kylen Ly'selle is the boy emperor of Draconia, a futuristic fantasy planet where dragons take humanoid form with wings and tails or shift into enormous beasts. Its people wield magic, beams, fire, flight, super speed, and super strength, with martial arts woven into the world. Kylen was forced onto the throne as a child after his father, Faust Ly'selle, murdered his wife to gain enormous power and was banished from Draconia. Now Faust wages war against the planet to reclaim his throne, making Kylen face the father who destroyed his family.
