Our dear author has forgotten his own continuity. A bunch of kids get kidnapped.
One is Max, who is explicitly described as 11-years-old. However, according to the established fact that the fall happened ~10 years ago, when his father Isaac was ~15, and Max was born when Issac was ~20, the absolute oldest Max could possibly be is 6.
It is talked about repeatedly that Joshua Ragland is now 34 and that the fall happened when he was 24. It's not a matter of misinterpreting text. The author just isn't paying attention, which is a bummer.
Also, when did Luke have a second daughter?
None of this makes sense.
