Tomorrow, and tomorrow, and tomorrow by Gabrielle Zevin

Two kids meet in a hospital gaming room in 1987. One is visiting her sister, the other is recovering from a car crash. The days and months are long there. Their love of video games becomes a shared world - of joy, escape and fierce competition. But all too soon that time is over, fades from view. When the pair spot each other eight years later in a crowded train station, they are catapulted back to that moment. The spark is immediate, and together they get to work on what they love - making games to delight, challenge and immerse players, finding an intimacy in digital worlds that eludes them in their real lives. Their collaborations make them superstars.
