Lamb traces the self-discovery of David Lamb, a narcissistic middle-aged man with a tendency toward dishonesty, in the weeks following the disintegration of his marriage and the death of his father. Hoping to regain some faith in his own goodness, he turns his attention to Tommie, an awkward and unpopular eleven-year-old girl. Lamb is convinced that he can help her avoid a destiny of apathy and emptiness and even comes to believe that his devotion to Tommie is in her best interest. But when he decides to abduct a willing Tommie for a road trip from Chicago to the Rockies, planning to initiate her to the beauty of the mountain wilderness, they are both shaken in ways neither of them expects.
Lamb is a masterful exploration of the dynamics of love and dependency that challenges the boundaries between adolescence and adulthood, confronts preconceived notions about conventional morality, and exposes mankind's eroded relationship with nature.
