From the best-selling author of The Dog Stars and The Painter, a luminous, masterful novel of suspense—the story of Celine, an elegant, aristocratic private eye who specializes in reuniting families, trying to make amends for a loss in her own past. Working out of her jewel box of an apartment at the base of the Brooklyn Bridge, Celine has made a career of tracking down missing persons, and she has a better record at it than the FBI. But when a young woman, Gabriela, asks for her help, a world of mystery and sorrow opens up. Gabriela's father was a photographer who went missing on the border of Montana and Wyoming. He was assumed to have died from a grizzly mauling, but his body was never found. Now, as Celine and her partner head to Yellowstone National Park, investigating a trail gone cold, it becomes clear that they are being followed—that this is a case someone desperately wants to keep closed. Combining the exquisite plotting and gorgeous evocation of nature that have become his hallmark, with a wildly engrossing story of family, privilege, and childhood loss, Peter Heller gives us his finest work to date.
