This book was fine, but honestly I didn't care that much. I'd much rather have skipped this entirely and gone straight to Winter for the climax of the series (although this probably has some important, or at least relevant, information for Winter). It felt like a delay of what I really cared about. I thought it would be more focused on humanizing Levana, but she was just as sociopathic at 15 as she was in the main series. And to be honest, not all that interesting. I'm really glad it was short.
