Not Pierce's strongest book, but I enjoyed it more than some in her Circle Opens series. I liked Evvy, and similarly to Will of the Empress I was left wanting to read more about the characters' war experiences. It sounds like that book will be released next year. 
 I read the book version, not the audio, and that seemed to make a difference if I'm to go by other peoples reviews. I liked this (short!) glimpse into what could have just been a minor side character, and into the purpose of the Temple. The story probably could have been improved with some length, room in which to fit more character development.
