The slightly dysfunctional family in this book and the way they are making the best of a bad situation. After a marriage breakup they are forced to move across the country and squeeze in with Grandma in her tiny house by the train tracks.
“When Katy hit the curve she took off like a kite,
High over the treetops on her first and last flight,
That would quickly have ended poor Katy caboose
If it hadn’t been for two towering spruce.
The caboose became caught in a very tight squeeze
Between the tall trunks of two evergreen trees.”
