In If Clara, nobody stands on firm ground. Daisy, a writer confined to her home, her leg in a cast from hip to ankle, receives a parcel containing the manuscript of a novel about a Syrian refugee and is asked to pose as its writer. Julia, the curator at the Kleinzahler Gallery, has no idea that her sister, Clara, has written a novel. However, she does know that Clara suffers from a debilitating mental illness, is unpredictable, and lapses easily into hostility. Maurice's life is changed by an art installation involving a pair of binoculars welded to the wall through which visitors are invited to observe passersby outside. An ultralight aircraft's collision with a quiet lawn brings them all together. If Clara explores the emotional weight of friendship, the complexity of family, and people inextricably entwined.
