"What if we cannot know even those we love best? In Mapping the Edge, Sarah Dunant writes with wonderful intelligence about the dark intricacies of motherhood, friendship, love, and obsession. A brilliantly plotted, ruthlessly intelligent, and highly readable novel."
--Margot Livesey, author of Eva Moves the Furniture

"[Dunant] plots with remarkable intricacy [and] is a master at creating anxiety and mystery." --The Washington Post

"Thoroughly satisfying . . . departs from the usual thriller formula . . . but it contains its own full array of surprises. . . . Dunant's feel for the geography of bed and willing flesh is a pleasure. . . . In moments . . . that delve into the subtleties and varieties of love and desire, Dunant emerges as a shrewd observer."
--The New York Times Book Review
