Continuity mistake: In Chapter 4, Garraty thinks about Jan and her long, dark hair. Later, in Chapter 6, he once again thinks of her, this time with her long, blonde hair.
Continuity mistake: Ray Garraty is 16 when he participates in The Long Walk, and it is also mentioned in Chapter 1 that his father had taken him to see a Long Walk when he was ten. However, in Chapter 7, he thinks about how his father had been taken away eleven years ago, never to be seen again. So when did Garraty's father disappear? Five years ago or eleven years ago?
Factual error: In Chapter 13, it is said that April 31st had been the final day to drop out voluntarily. April only has 30 days.
