Unknown: Dr. Martin Harris awakens after a car accident in Berlin to discover that his wife suddenly doesn't recognize him and another man has assumed his identity. Ignored by disbelieving authorities and hunted by mysterious assassins, he finds himself alone, tired, and on the run. Aided by an unlikely ally, Harris plunges into a deadly mystery, forcing him to question his sanity, his identity, and just how far he's willing to go to uncover the truth.

Edge of darkness: The bullet that killed his daughter was meant for Boston cop Thomas Craven. That's what police brass and Craven himself think, but that's not what the investigation finds. Clue after clue and witness after witness, the search leads him into a shadowy realm where money and political intrigue intersect. If Craven wasn't a target before, he, and anyone linked to his inquiry, now is.
