Celine is not your typical private eye. With prep school pedigree and a pair of opera glasses for stakeouts, her methods are unconventional but extremely successful. Working out of her jewel box of an apartment nestled under the Brooklyn Bridge, Celine has made a career out of tracking down missing persons nobody else can find. But when a young woman named Gabriela employs her expertise, what was meant to be Celine's last case becomes a scavenger hunt through her own memories, the secrets there and the surprising redemptions.

Gabriela's father was a National Geographic photographer who went missing in Wyoming twenty years ago and while he was assumed to have been mauled by a grizzly his body was never found. Celine and her partner set out to Yellowstone National Park to follow a trail gone cold but soon realize that somebody desperately wants to keep this case closed. Combining ingenious plotting with crystalline prose and sweeping natural panoramas, Peter Heller gives us his finest work to date.
