It's the Victorian time in Great Britian, tight corsets that make it difficult to breath but tighter conventions makes it also difficult to live. A magical place called The Realms offers freedom to be who you are. But The Realms is also a dangerous place. Gemma holds all the power and has no idea who she can trust.
A masterfully written book in story, character and in the beauty of language.
If Libba Bray has written it, you should read it.
