The Kept King by Ryan D. Meier

Autumn has come to the kingdom of Harlow’s Hill. Life in the northern hills was peaceful, serene, and trouble-free.
But for King Thomas Hawke, it wasn’t that simple. Since childhood he had been stricken with a mysterious illness; one with no known cause, and no known cure. It repeatedly took a heavy toll on his body; however, nothing was more devastating than the loss of his memory.
After each episode, the King is left to reconstruct the fragments of his life, hoping that one day his memories might return. As the years stretched on, his illness only grew worse – threatening his family line that still required an heir.
One day, a mysterious new woman, Kate, arrives. Mundane life as the King knew it was over. Join Thomas and Kate as they unravel the mysteries of Harlow’s Hill, changing everything they know about who they were, who they are, and who they will be.
