With its propulsive drive, vividly realized characters, and profound observations about soul and society, Pulitzer Prize-finalist Susan Choi's latest novel is as thrilling as it is lyrical, and confirms her place as one of the most important novelists chronicling the American experience. Intricately plotted and psychologically acute, A Person of Interest exposes the fault lines of paranoia and dread that have fractured American life and asks how far one man must go to escape his regrets. Professor Lee, an Asian-born mathematician near retirement age would seem the last person to attract the attention of FBI agents. Yet after a colleague becomes the latest victim of a serial bomber, Lee must endure the undermining power of suspicion and face the ghosts of his past.
