A poignant---and funny!---allegory of sorts about climate change. The main conceit of the book is that the children, full of gumption and resolve, switches roles with their parents, who are despondent and lazy, more preoccupied with sex and booze than with fixing what is wrong. The children are Greta Thunbergs, and we, the current generation, are the parents. They are angry at us for not having the will to fix things while we still have some time.
