Growing up in an isolated cabin in Montana in the mid-1990s, Jane knows only the world that she and her father live the wood stove that heats their home, the vegetable garden where they try to eke out a subsistence existence, the books of nineteenth-century philosophy that her father gives her to read in lieu of going to school. Her father is elusive about their pasts, giving Jane little beyond the facts that they once lived in the Bay Area and that her mother died in a car accident, the crash propelling him to move Jane off the grid to raise her in a Thoreau-like utopia.

As Jane becomes a teenager she starts pushing against the boundaries of her restricted world. She begs to accompany her father on his occasional trips away from the cabin. But when Jane realizes that her devotion to her father has made her an accomplice to a horrific crime, she flees Montana to the only place she knows to look for answers about her mysterious past, and her mother’s San Francisco. It is a city in the midst of a seismic change, where her quest to understand herself will force her to reckon with both the possibilities and the perils of the fledgling Internet, and where she will come to question everything she values.
