Mistakes

A mistake, also known as a goof or an inconsistency is when sources contradict each other.

List of mistakes

 * In Light, the original population of the FAYZ is 332. In Hunger, Sam says that he is responsible for 331 people after E.Z. 's death. This would suggest that the original population was 355, as 21 kids died in Gone, 2 kids died between Gone and Hunger, and 1 kid died at this point in Hunger. And according to the Spanish cover for Hunger, the original population is 357.
 * In Gone, Drake's whip is on his right arm, but in book covers his whip is on his left arm.
 * In Hunger (chapter thirty eight), Dekka states that she only fell in love with Brianna after being by her side in the cement blocks during the FAYZ, but in Lies (chapter three) she states that she had fallen in love with Brianna immediately when meeting her at Coates Academy.
 * Mistakes are repeatedly made with different characters' ages, such as in Fear when Sam is said to be barely fifteen when he is in fact just under sixteen at the youngest.
 * Dekka never remembers her dreams, but in Light she dreamed about Brianna and apparently remembered it.
 * In between Gone and Hunger they used a Christmas tree found in Astrid's attic, when her house had already burned down.
 * Edilio is implied to have a crush on Lana in Gone, despite being gay.
 * Sam and Astrid both note at different points during Gone how similar Sam and Caine look, but Sam later says in Light that he and Caine don't look much alike.
