The plot is set in a world where the average person has five secrets they’ve never told a living soul; get just one of them, and you have control over its keeper. Hedrick is a highly skilled mercenary who trades in exactly these kinds of secrets — staging elaborate near-death experiences to get powerful people to unknowingly confess to theirs. His own biggest secret is that he desperately wants out, and when his employers find out, he’ll be killed. So when he’s sent on a strange mission to extract a secret from his former mentor, he knows: figuring out the secret being kept from him will be the only way he gets out alive.
