The Cain Conspiracy — Mike Ryan

Shot in the head and recovering from brain surgery, Delta Force soldier Thomas Nelson wakes up in a military hospital unable to remember who he is. Faced with going through recovery alone, with no family that he's aware of, he is recruited by a top secret government agency. Project Specter is tasked with eliminating targets they deem to be a threat to the United States. Their goal is to turn Nelson into a super assassin named Matthew Cain. Cain's first mission is supposed to be a piece of cake. Just take out an escaped fugitive in Honduras who's on the run for the rape and murder of a little girl in New York. There's only one problem...somebody beat him to it. Everything is not what it seems as Cain gets mixed up with an international arms dealer and an ex government agent who's gone rogue and supposed to be dead.
