I read anything that's nailed down, or even just moving slowly. Cereal boxes, candy wrappers, all genres, etc., and I don't always have much time for arbitrary distinctions like literary fiction vs. genre fiction.
This book isn't written as a typical novel...there is no growth or character arc for the narrator, a scientist who is writing a series of letters to his daughter, Beatrice. The letters tell her the story of how a "substance" was developed that ensured the birth only of baby boys.
Interesting premise, but Maalouf doesn't actually describe the effects very much, let alone the effects on the women themselves. When women are scarce, particularly in patriarchical societies, guess what happens? Do the women rule, have power, control their own bodies? Hell, no. They're kept under lock and key and lose all agency. But he doesn't tell his daughter that. Nope, it's all about the poor men--they can't find brides, etc.
I'd recommend this one for people who liked The Handmaid's Tale, but don't expect standard storytelling--the father's "voice" is affected and academic.
