When park ranger Anna Pigeon embarks on a thrilling subterranean rescue mission, she confronts personal demons and a multitude of life-threatening dangers, not all of them from the hostile terrain. A fellow ranger is injured in a suspicious accident while exploring the mostly unmapped Lechuguilla Cavern in New Mexico's Carlsbad Caverns. During a fleeting moment of consciousness, the victim calls for Anna. Battling her paralyzing fear of small spaces, Anna descends into the lifeless underworld to uncover what really happened. As Anna wriggles through cramped tunnels and climbs rocky precipices, she discovers treachery and destruction lurking in the inky black just beyond her headlamp. Veteran narrator Barbara Rosenblat provides the perfect voice for the courageous, but very human, park ranger and her colleagues.
"Barr brings the intricate, fascinating, and deadly underground world of spelunking into close and intimate focus using Anna's divergent emotions of awe and near terror as she works her way through the total blackness. Readers are immersed in the setting, and Anna's claustrophobia, tangibly intense at times, keeps the tension of the plot tautly controlled." ( School Library Journal)
"Barr's gripping prose never loses its hold: we feel Anna's fear acutely, and the tension of the rescue is palpable." ( Booklist)
