I can't help but give this series 5 stars. It has me hooked the entire time. 
 I'm going to be focusing more on the beginning and the ending of the novella. don't worry there won't be spoilers. To avoid character names however, I will be putting this as spoiler free just encase someone wants to know NOTHING about who is involved, etc. 
 What was so shocking to me in the beginning was (view spoiler)[ I was surprised to read the first paragraph. It's a story about Jellia! I was so thrown off by this. I really wasn't expecting it. I almost hoped it was about Mombi, but too soon so it makes sense. I also half excepted it to be from Dorothy's perspective again, just like No Place Like Oz. I'm glad it wasn't though. Jellia's perspective hit the spot perfectly! It was a grand short read. Although it seems repetitive (it related to Amy's story on several occasions), it was still nice to be able to read it again. (hide spoiler)] 
 What I like about this novella is ((MAJOR spoilers! Only read if you have finished this novella and Dorothy Must Die)) (view spoiler)[you get to revisit characters that have died in the future tense. Since these books are set in the past, it's humbling to read about Jellia and Gert again! (hide spoiler)] 
 What I find to be a major downer (so much so I almost want to give this 4 stars) is how Paige's books and novellas end. I felt like it ended so abruptly, and definitely could have included at least a few more pages. It's only 63 pages; at least 5 more pages would have been nice on how (view spoiler)[ they chose Jellia as a spy. (hide spoiler)] 
 Overall, I think it's important to read the novellas in order of publication with the books. Not entirely necessary, but it just adds to the excitement of the story that much more!
