I read Dorothy Must Die before I read the prequel and I have to say as I was reading this prequel, I knew the outcome, and I thought it was very interesting to read it that way. (view spoiler)[The story starts off with Dorothy's sweet sixteen. As you are reading this, you start to feel very sorry for Dorothy because these girls are so mean and rude and just plain awful. And Dorothy's supposed best friend has become best friends with the mean girl, blah blah. No believes her about her travels to Oz. She ends up storming into her room and what does she find but a strange package that contains ruby shoes that we can only assume was given to her from Glinda. So she claps her heels together 3 times and is transported back to Oz to the same spot she landed on the first trip, but this time with her Aunt Em and Uncle Henry. It had been two years (in our world) since Dorothy had been back to Oz, but more like ten years in the world of Oz. They go to where the Scarecrow lives and Dorothy tells him of her strange seeing of Glinda asking for help. The Scarecrow precedes to tell Dorothy of how shortly after she left, Ozma, the true princess of Oz came back and is now ruler over Oz. Dorothy and her family and the Scarecrow travel to the Emerald City where they meet Ozma. Dorothy becomes jealous of all the power Ozma has. At the end Dorothy's shoes help to give Dorothy magic but it is evil magic and Ozma tries to take it from Dorothy and send Aunt Em, Uncle Henry, and Dorothy back home in the house that originally brought Dorothy to Oz. This results in Dorothy being enraged and attempting to throw the at Ozma which then results in the house landing on Dorothy's Aunt and Uncle killing them. Dorothy is so upset she tries to kill Ozma, however, since Dorothy can't kill Ozma because it will kill Oz itself, she settles for making Ozma brain dead. Glinda comes back and we get very creepy vibes from her. (hide spoiler)] Throughout reading this prequel I had no doubt in my mind that it was in fact Dorothy telling the story. Danielle Paige did a fantastic job of portraying this and her other characters. I throughly enjoyed the story. However, I did find it a little bit modern at the beginning about the way the girls were acting. That was such a small part of the prequel that it didn't effect it that much. Another thing was that it was quite long for a prequel. Almost 200 pages, but that made sense because Danielle Paige had to explain why and how the magic of Oz got to Dorothy's head. If you choose to read the prequels before Dorothy Must Die, I think that it is totally fine, also if you choose to read the prequels after Dorothy Must Die (like I did), I think that is totally fine as well, just so long as you read this series because it is FANTASTIC!!! 
 HAPPY READINGS!!!
