In the rugged Pacific Northwest of the United States lies the Olympic National Forest - a vast expanse of impenetrable darkness and impossible beauty. From deep within this mysterious woodland, a six-year-old girl appears.

Speechless and alone, she offers no clue as to her identity, no hint of her past. Having retreated to her hometown after a scandal left her career in ruins, child psychiatrist Dr Julia Cates begins working with the extraordinary little girl. Naming her Alice, Julia is determined to free her from a prison of unimaginable fear and isolation, and discover the truth about Alice's past.
