One freezing December day while studying at Harvard, Sam Masur exits a subway car and spots Sadie Green amongst the crowd of people. He calls out to her, but, at first, she pretends not to hear him. She then turns around and, thus, begins a collaboration that will launch them both to stardom. They borrow money, call in favors, and, before graduation, they create Ichigo, a game that allows players to leave the confines of their bodies and begin anew. This complex novel looks at technology and human experience in an unforgettable way.
