omg I loved this.
Perfect start to 2018. I think this is possibly my new favourite Marie Lu book. 

The world Marie creates is so vivid and beautifully written you can't help but get lost. The world came alive as you read. 

I loved Emika. I'm excited to see where her character goes in book 2. I'm 50/50 on what I feel about Hideo, for so much of the book I loved him but then the end made me think maybe he's not such a good guy. But I still want to like him. The struggle. 

I highly recommend this. Possibly a new all-time favourite book.
