The Skinny: 
 Don't betray powerful people. 
 The Fat: 
 I kind of hate myself for reading this book. 
 Why might you ask? Well, now I have to wait a whole fucking year in order to read the next book!!! Why do I always do this to myself? I really just need to start reading books only when the whole series is out. 
 The Young Elites (TYE) left off with Adelina and her sister being banished from the Dagger Society after Enzo's untimely death. The Rose Society (TRS) revolves arounds Adelina's struggle to gain her own group of Young Elites and her plot for revenge against all who have wronged her. Some new characters emerge and let's just say a lot of shit goes down really quickly. There are betrayals up the wazoo, and Adelina/readers won't know who to trust. 
 I loved reading TYE and TRS was no different. In TRS readers get to read some of Maeve, Teren, and Raffaele's POV, but similarly to TYE, most of the book is told in Adelina's POV. I wish that readers got to see some of Violetta and (view spoiler)[ Magiano (hide spoiler)]'s POVs since the two spend so much time with Adelina it would have been interesting to watch her change through their eyes. 
 Marie Lu states in her author's note that TRS is the darkest book that she has ever written, and with the amount of manipulation, torture, death, abuse, and lack of conscience characters have, it is no wonder that Lu said such things. TRS is definitely a book that can push the boundaries of YA literature. The sequel to an origin story about a villain, TRS is not a book that you'll want to miss. 
 Technical rating: 4.5/5, because although I really enjoyed this book, it wasn't quite as shocking as TYE.
