I'm crying at how this book was marvelously written.
Halfway through the book, I thought that there's not much difference between Scythe and Thunderhead especially since this is the former's sequel. However, I was not prepared with the scenes presented by the last 1/4 of the book. Everything was heart pounding and unpredictable at that point. I loved the characters more than ever and I sort of pitied the Thunderhead as well.
In simple words, I say that this book SHOOK me. It shook me so much that I can't wait for The Toll to be released.
Oh, one last note. The audiobook is fantastic! Having both the book and the audiobook is so worth it.
