A Coronation of Kings is a free kindle book from Amazon. From the description:
With his world in ashes Tristan Listar is left fighting for his life. As the island of Valaar slips beneath the tides of tyranny, Tristan must save himself… and his people.
Tyrants will rise, armies will assemble, and the winds of magic stir ominously. When the dust settles and the age of uncertainty is at an end, who will wear the Crown of Kings?
