Glitches - Marissa Meyer This review is full of spoilers.

I was really glad that Marissa Meyer wrote this novella because I think that there were a lot of holes in Cinder's background. I really enjoyed reading about where (ish) she came from, and how things were for her starting out. I particularly enjoyed that it was Cinder who put Iko back together. I thought the scene where Garan was taken away was pretty heartbreaking, and the whole short makes you wonder what it would have been like if he had lived.
I would definitely recommend this to anyone who enjoyed Cinder.
