The Innocent Mage: Kingmaker, Kingbreaker Book 1

The Innocent Mage - Karen Miller Asher is born the son of a fisherman but has bigger dreams about what to do with his life. He rescues the prince and becomes a friend. His life becomes complicated and involved with the politics of the kingdom. There's hidden magic involved in the plot and prophecy. It's pretty predictable in parts but I did enjoy the story.
