I haven't read Cixin Liu yet and it's about time I do. I love science fiction and have heard so much about his books. Supernova Era sounds like Michael Grant's Gone series and I'm hoping it's very different besides children ruling because I wasn't a fan of those. It has a very big character list which can be daunting so I'm hoping it doesn't get bogged down in characters. I love the cover, it's very eye-catching, you definitely know it's a science fiction book.
