The Dark Moon — Julia Gray

The birth of the Emperor's son had been prophesied many years before. The child would be the Guardian, savior of his people. What had not been foreseen was the fact that there would be two imperial children born that night. Jax, the firstborn, is raised in the Imperial Palace and groomed for his role as the future leader of The Floating Islands. Terrell, second born and hideously disfigured, is banished to Havenmoon, where he will spend his life unaware of his birthright. Both have hidden talents, but is either the true Guardian? When the Islands begin to spin out of control, in danger of colliding with the mainland, the prophecy begins to unfold.
