Accompanying celebrated academic, Katherine Solomon, to a lecture she's been invited to give in Prague, Robert Langdon's world spirals out of control when she disappears without trace from their hotel room. Far from home and out of his comfort zone, Langdon must pit his wits against forces unknown to recover the woman he loves.
