I’ve heard it said that science fiction is a “literature of ideas”. I never liked this. All literature is ideas. Thus, I would paraphrase to say science fiction is a literature wherein ideas that do not (yet) exist in reality often take priority over the realism of character, emotion, dialogue, etc. After all, alien species, extraterrestrial planets, radical technology, and alternate forms of society often receive more attention from science fiction writers than the characters around them. Science fiction by default, Herve Le Tellier’s The Anomaly (2022) nevertheless subverts this mode by putting its weight behind typically less-prioritized elements—ideas, as they were.
To say precisely how The Anomaly is science fiction is to spoil the novel. Therefore, it is a good time to pause and say if this is one of the first reviews you have read of The Anomaly, be cautious reading additional reviews if you are concerned about plot spoilers. The novel hinges around an “idea” that is revealed at about the halfway mark. I have read reviews which discuss it in nonchalant fashion, but be aware it is the hook on which the plot is hung.
