1000000/10 it's so good. Sci-Fi themed + historical theme. Wow . It's such a mind-fuck read, where you really don't know what anyone is thinking about, or who is trust worthy. The drama is amazing. And the lessons omg the lessons of Uona's dad to Uona is so sweet and really stuck out to me "the most important thing is our heart". Damn.
