|aA young Puritan woman travels to the New World with her unwanted new husband. Alan Turing, the renowned mathematician and code breaker, writes letters to his best friend's mother. A Jewish refugee and professor of computer science struggles to reconnect with his increasingly detached wife. An isolated and traumatized young girl exchanges messages with an intelligent software program. A former Silicon Valley Wunderkind is imprisoned for creating illegal lifelike dolls. Each of these characters is attempting to communicate across gaps -- to estranged spouses, lost friends, future readers, or a computer program that may or may not understand them.
