“Lock has embarked on a fascinating intellectual and artistic endeavor: engaging key American writers from the 19^th century through a series of speculative historical novels. . . . In his latest installment, the author examines the life and work of Henry David Thoreau. . . . There is no sermonizing here, just thought-provoking juxtapositions and conversations. Ultimately, what emerges is a unique and affectionate homage.”
