Chapter chat mapmakers race

Map Makers race is about a family that lost their parents on a train and have been waiting 20 something days to find them.
Chapter chat this year has been pretty good, But my favourite was fish in a tree which I heard in the batten team. I'd rate the map makers race it about a 5 out of 10 didn't really show much interest. I don't know much of the characters. I wasn't exactly sure what happened in the story.
