So this is easily my favourite Marie Lu book. It reminds me a lot of the blend of history and fantasy from [b:The Light Between Worlds|34842042|The Light Between Worlds|Laura E. Weymouth|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1526501437l/34842042._SY75_.jpg|56074375] which is a huge favourite of mine. There was a lot of guessing and twists but the whole time you were like "but wait...it's a dream world...right?" I love that Lu didn't shy away from how sexism has in fact resulted in the loss of some amazing pieces of music, literature, inventions, etc simply because they weren't allowed to do that. I was especially in love with how sickness was used to control the characters.
