At twenty-three Alice Hare, a loner, arrives in New York with only the vaguest of plans: to find a city to call home. Instead she discovers the online profile of a Japanese writer called Mizuko Himura, whose stories blur the line between autobiography and fiction. Alice becomes infatuated with Mizuko from afar, convinced this stranger's life holds a mirror to her own. Realities multiply as Alice closes in on her "internet twin," staging a chance encounter and inserting herself into his orbit. When Mizuko disappears, Alice is alone and adrift again. Tortured by her silence, Alice uses the only tool at her disposal, writing herself back into Mizuko's story, with disastrous consequences.
