TOXIC DOOM  When a British CIA operative in Hong Kong dies moments after sending a cryptic text message, the government needs a special kind of help to deal with the foul play-under-the-radar Mack Bolan expertise. Sent to decipher the coded message and track down the cause of the agent's murder, Bolan discovers someone within the agency leaking information to a known arms dealer.  Ambushed at every turn, Bolan's survival instincts have to work double-time to keep him and the three-person team assigned to the case alive. But their lives aren't the only ones at stake. There's a new weapon of mass destruction on the market, a Sleeping Dragon, and a fanatical Arab plans to use it to take back Libya, killing millions in the process. His enemies believe they know their devils, but they haven't met the Executioner.
