The Murders Of Molly Southbourne by Tade Thompson

A woman discovers that whenever she bleeds an identical, homicidal duplicate of herself is created, and her life becomes a grim ledger of hunting and killing these copies to stay alive; raised under surveillance and forced into a brutal cycle, she becomes both predator and prey while wrestling with identity, memory and the moral cost of surviving as the boundary between original and replication steadily collapses.
