Once there was a world’s end.

The forests burned, the lakes and rivers dried up, and the oceans swelled.

Then came a plague, and fever spread across the globe. Families died, violence reigned, and man killed man.

Next came WICKED, who were looking for an answer. And then they found the perfect boy.

The boy’s name was Thomas, and Thomas built a maze.

Now there are secrets.

Why, why, whyyyyyy do I keep torturing myself with these novels?

Deeeeeeep Breaths

This book added nothing of value to the entire series. Why? Cause we're able to piece together the entire plot from blatantly obvious foreshadowing (or would that be back-shadowing?) from the original trilogy.

Secret Government Agency to get rid of virus? Yup, figured that one out in the first book.

Maze is designed by children? Hinted at and later confirmed in book 2.

And on....and on.........and on........

The one person that instantly came to my mind when I saw this book was Newt.

Imagine this: Multiple POVs. Newt's desperate thoughts. Physical pain + psychological pain. (and double it all because he's my favorite)

“You look bloody fantastic for three in the morning.”

“WICKED was never going to stop. They were never, never going to stop.” Apparently, neither was Dashner. I have a strange attachment to this series, despite disliking most aspects of it. The Maze Runner was one of the first young adult series I read, so it’s a shame I have such negative opinions towards it now. The story itself is intr

Um. I sat here forever trying to figure out what I want the stars to be. I will just go with the three star rating.

I LOVED reading about the group again and reading about how some of them were taken and their ages. Those WICKED people really are evil. I'm guessing they picked the right name.

I just can't believe the kids lived all of their years there and just ugh.

And that creepy guy coming down the hall, "Save Me, Save me" Well, I don't remember if that's exactly what he said but along those

I thoroughly enjoyed this Maze Runner prequel! We get insight into Thomas and Teresa's lives as they grow up within WICKED and all the brain washing that comes with it . We get to meet all the characters from the original trilogy - all before they enter the maze.
It was really interesting to view things from this perspective, to watch the build up to

This book was definitely the missing piece in this series, but I was left with more questions after reading this then going in. This book lacked the tension and twists the previous books had and it had some boring and weird chapters. It wasn’t renewing enough for a book that was supposed to have all the answered. I’m really disappointed. The three stars are for Thomas and the other Gladers, the prologue, for the amazing writing style James has and for the few answers I did get.

For an ardent dystopian fan such as myself, ‘The Maze Runner’ series is the gift that keeps on giving. Not only are there three books in the original trilogy, but two full-length prequel novels.

This takes place directly before the events that occur in The Maze Runner, yet should be read last, as per Dashner’s specific instructions. The book chronicles the conception of the WICKED organisation, as well as how Tho

I cannot tell you just how much I needed this book. I loved it so friking much! I was left feeling all emotional after reading The Death Cure, this just brightened me all up. It was so cute that Newt, Minho, Thomas, Teresa, Chuck and Alby were friends before they got sent into the maze.
I'm actually mad at myself for finishing it in a day. This is one of those books that should be read slowly but I just could not help myself.

Well that was heart wrenching. Seeing my babies as babies basically killed me. ALSO, that ending changes EVERYTHING. I'm pretty sure I just stared at the book dumbfounded for a few minutes. Oh, and another thing. Chuck is my favorite. (Don't tell Brenda, she's my second favorite) ...more

i feel like this book was the missing piece in this story but it still left me with so many questions that i need answered. I've been waiting for another prequel like this that answered my questions from the trilogy and i wasn't disappointed of course.

I LOVED this book, finally the old group is back and this is where and when everything started.
We meet our characters in here since their very beginning and very first interactions with WICKED.
It was so informative, we discover everything that is related to the main purpose of why these mazes were created and we go tr

Two years ago, I read the whole Maze Runner trilogy in a month. I'm serious. I bought the three books all together and read them literally non-stop. I clearly liked it but I've never been fully enamoured of it. Then, I read The Kill Order, the first prequel, some months later and I didn't appreciate it as much as I did with the original trilogy. I still think it's the worst in the series and my enthusiasm somehow diminished. Then the films came out and my opinions started to differ. Sometimes I ...more

It really saddens me that the only book worth my time after the first one was the fifth entry in the series. As prequel to The Maze Runner, it gives a great insight of how the maze was built and some of the motivations the main characters follow.

When I started this and found out it was going to be about Thomas and Teresa I was really nervous. I loved The Maze Runner, I thought The Scorch Trials was quite good, but I was so disappointed by The Death Cure ....
This was such a turn around from the last book and I am so happy to say it exceeded all my expectations!
I enjoyed watching Thomas and Teresa grow up and develop in WICKED headquarters. You can see their character development so much better! As a result, I still hate Teresa!! Ugh she

I started this book with the intention of pacing out my reading of it. Then I started reading it. Three days later, I'm finished.

I started out loving this book. Newt's prologue at the beginning was heartbreaking and emotional: a great way to start. As the book went on, I was happy to see some of the same humor and character personalities that made me love the Maze Runner, Scorch Trials, and Death Cure.

Once I got to the last fourth of the book, I was enjoying it still but rather disappointed th

Not quite as horrendous as The Death Cure, but far from the greatness of The Maze Runner. For a book that is meant to answer all of your questions, it spends a decent 200 pages talking about absolutely nothing.
Even the writing style was weird - everything was repeated and described in excruciating and unnecessary detail. It's as if Dashner needed to reach a certain word limit before submitting his draft - everything was repeated and most of the storyline was just pointless. A big disappointment

James Dashner has done it again! Another book to add to my beloved series!

Thomas looked up at his group of friends, then looked at Chuck.
"A man once gave us a message that we'll never forget," he said. "'WICKED is good.' I think our lives might have a lot more purpose than we could ever know. I think we need to remember to look at the big picture."

- I'm really happy that this book was released after I read the whole series because I don't think I would have enjoyed the many plot twists if I read

Before I even started reading this book I already know how emotionally it will be but boi It was definitely more than that …and Newt first chapter oh my god I don’t know what my feelings are doing !!
Honestly this prequel change a lot of things ! I’ll never read the maze runner the same way I did !!
I really liked when Thomas and the gladers started their friendship especially newt and minho they were awesome I only wished we could learn more about them.
