Tasked with writing the preface to a reissue of her late husband's long-out-of-print novel, Edna also finds herself taking care of a vacationing neighbor's pet rat, an aquarium of fish, and an apartment full of potted plants. Sitting at her typewriter day after day, her mind drifts in a Proustian marathon of introspection. What eventually unfolds, as if by accident, is the story of a marriage and a portrait of a mind pushed to its limits. Is Edna's preface an homage to her late husband or an act of belated revenge? Is she the cultured and sensitive victim of a crass and brutally ambitious husband? Or was Clarence the long-suffering caretaker of a neurotic and delusional wife? The unforgettable characters in Sam Savage's two bestselling novels Firmin and The Cry of the Sloth garnered worldwide critical acclaim. In Glass, Savage once again creates a character simultaneously appealing and exasperating, comical and tragic.
