I was actually completely unaware that this novella existed, until I finished reading my paperback copy of Cinder and saw that it was included at the end. I'd like to thank the publisher for doing so, because otherwise I would have missed it!If you're wanting some background about Cinder's introduction into the Linh's lives, then this novella is a must-read. I loved Cinder's uncertainty and fear, and the fact that - even without Adri's vehemence against her - Cinder was already acutely aware of how different she was from Peony and Pearl, and how she didn't really fit in. I did love that Peony was so accepting of her, wanting to play with her, spend time with her, and just talk and laugh with her. It makes the circumstances in Cinder all the more poignant and heart-wrenching. I also adored the early look at Iko, and that it was Cinder that brought her back to "life". I can only hope she reappears soon in Scarlet because I desperately missed her humor and good cheer! I can't help but wonder, though, if Adri's opinion of cyborgs - and Cinder specifically - would have changed if Garan hadn't contracted Letumosis? Alas, that is one question that shall never be answered.While I didn't find Glitches to be completely and utterly amazing, I would definitely recommend it to anyone who enjoyed Cinder, just for the little bits of added information, and some background on the world. It doesn't really answer any burning questions, but is a nice, short, worthwhile read nonetheless.***To see more of my reviews, please visit me @ Read and Reviewed!
