The Maze Runner Files

The book adds so much depth to the series, but I wonder how much was planned from the start versus developed later. Did the lore grow organically or was it mapped out early?

Learning more about their pasts and the secret experiments made me see their choices differently. Did this deepen your connection to them or feel like too much info?

Some parts felt fast-paced and others slower as they explained details. Was this balance effective or did it drag in places?
