In Anna Kozlova’s novel “F20,” the heroine lives with the terrifying diagnosis of “schizophrenia.” Reading this ruthless, funny, and deeply dramatic text, you can’t help but wonder: who, in fact, should be considered “normal”? The “National Bestseller—2017” prize. This novel isn’t about schizophrenia, but about everyone else living alongside the “normal” majority and pretending they don’t exist. (Anna Kozlova) “F20” can be read as a medical case history, but— as is typical in works with a crazy main character— the illness isn’t separate from one person, but from society itself. (Elena Makeenko) The book is extremely honest—both toward the main heroine and toward the reader. (Vladislav Tolstov) Madness has been written about in many masterpieces, but against their background, Kozlova’s book is the only one truly insane.
