For the most part I liked The Fate of the Tearling but I thought the ending was a terrible. 
 (view spoiler)[ I didn't like how the series finished with Kelsea going back in time and stopping everything before it really got started. It was a cop-out. An easy solution to a complicated story. It essentially made nearly everything that had happened in the books before this pointless, as they essentially never happened.... (view spoiler)[ (hide spoiler)] (hide spoiler)]
