OH MY GOD WOW WOW WOW LOVED THIS BOOK SO MUCH. This book was so well written, I expected almost none of the plot twists. Arthur being the mole was pretty obvious, but Catherine being a murder, Oliver going crazy and dying, red almost dying, the last chapter was literally so sad, but then the last few parts made up. The ending was a bit confusing since everything was happening at once, but it was still so exciting to read.
