The Fever Code is a prequel to the Maze Runner trilogy by James Dashner. It tells the story of how the Maze was built, what W.I.C.K.E.D. (the organization that put together these trials to try to find a cure to the Flare, a disease ravaging the Earth) was thinking, and how the participants in the Maze Trials knew each other before their memories were erased and they were put in the Maze. James Dashner joked that he hoped this book helped readers to forgive him for page 250 of The Death Cure, the third book in the series. Page 250 was heartbreaking, but it was probably one of the best, most emotional moments in The Death Cure, which was a disappointing end to the trilogy. However, The Fever Code was much better than The Death Cure. It answered some questions that readers had about the creation of the Maze and the role that Thomas, the protagonist, played in its creation. It was also really nice to see favorite characters alive that didn't make it through the main series.
My main criticism is that this book was from Thomas’s point of view the whole time, and it didn't have to be. The prologue was from Newt’s point of view, which was amazing, but then the rest of the story is Thomas. It would have been nice to see inside the minds of Newt, Minho, and Alby as they became friends, interacted with each other, and struggled to survive the Maze as they learned about their new surroundings. Instead, we get Thomas occasionally watching their activities in the Maze through cameras and feeling torn about what he's doing to help W.I.C.K.E.D. Though I have a problem with how that was handled, I feel that James Dashner did a good job overall. I would definitely recommend this book to fans of the series.
