I’ll give this three, or maybe 3 1/2, out of five. The novel is my first foray into climate fiction. No date is given for the events in this novel, but it must be in the near future. Narrated by 3 children rising to adulthood, it chronicles the events leading to their taking shelter from the ravages of climate change in the High House of the title, and of the love expressed by the adults raising them in preparing them and the house for what is to come.
