I had rather high expectations of this book, mostly because it had 2 authors. I went with the belief that 2 authors were definitely better than 1, no? Unfortunately, I was wrong. Perhaps one of the pitfalls of this book was because it had 2 authors. I felt that the book was longer than it should have been. Every single plotline that could be dragged on, was, and while the mythology surrounding Casters and the like was interesting, it became very confusing as well. I didn't find Lena and Ethan's relationship compelling and I suppose, that was one of the reason why I found myself struggling to get through 563 pages. 
 While I won't be discouraging others from reading this book, I myself am still not sure if I should read the sequel. 0.o
