The Tyrant's Heir (Desertera #3) | 
pickThis novel is the follow up that the second book of the series deserved. Even with a fourth novel in the series that remains unpublished, this provides a satisfying conclusion to the series on its own as it brings together elements from both of its predecessors and ties their loose ends beautifully. The world building gives way to character development, with a delicious conclusion that spans the entire series.
