In "Lolly Willowes, " Sylvia Townsend Warner tells of an aging spinster's struggle to break way from her controlling family--a classic story that she treats with cool feminist intelligence, while adding a dimension of the supernatural and strange. Warner is one of the outstanding and indispensable mavericks of twentieth-century literature, a writer to set beside Djuna Barnes and Jane Bowles, with a subversive genius that anticipates the fantastic flights of such contemporaries as Angela Carter and Jeanette Winterson.
