The novel “Circadian Algorithms” by Tom B. Night was published for the first time in 2022.

Madeline is the CEO of a startup that is in a crucial period for its success. Time never seems to be enough, so she undergoes a procedure that significantly reduces her need for sleep. She does so in secret, not even telling her husband, Darwin, because she knows he has his own reasons for doubting the procedure.

Initially, everything seems to be going well for Madeline, but an encounter with a stranger seems to mark the beginning of her problems in telling reality from dreams. When she confesses to her husband what she has done, Darwin reacts badly, and Madeline decides to divorce him. Darwin thinks something strange is going on, and soon it affects his life as well.
