Book 3 of Wild Era - David North

Kelin Wildfire’s new life is blazing with potential and he has a lofty goal: to become the Sovereign of Souls and the Lord of Reincarnation. The path is long and deadly, but for an Archmage to be reborn, his sight should be set higher than it was before, which means establishing a foundation that will allow him to surpass the level of his previous life.
