Elle Cosimano is an American author best known for the Finlay Donovan mystery series, a witty blend of crime, comedy, motherhood, friendship, and escalating domestic chaos. Her adult breakthrough, Finlay Donovan Is Killing It, introduced a struggling novelist and... single mother whose life spins into criminal absurdity after she is mistaken for a contract killer. Before Finlay, Cosimano wrote young adult suspense and fantasy novels including Nearly Gone, Holding Smoke, The Suffering Tree, and the Seasons duology, giving her work a darker foundation in secrets, danger, and emotional pressure. Across both phases of her career, she is known for fast pacing, sharp hooks, layered complications, and characters whose messy personal lives make the suspense funnier, riskier, and more human.
