Chris Ryan's Strike Back
John Porter resigns from the SAS following the aftermath of a rescue mission in Iraq on the eve of the American led invasion in 2003, where two fellow soldiers were killed, apparently by a thirteen-year boy Porter had failed to kill, leaving him responsible. Seven years later, Porter is "reactivated" following the kidnap of journalist Katie Dartmouth by the same terrorists he fought seven years ago, including the same boy: As'ad.

After locating the terrorist safe house Katie is being held in, Porter is also taken prisoner, and Hugh Collinson and a team at Section 20 have to act quickly before it is too late.
