Ghost Watch: A Vin Cooper Novel 4

Special Agent Vin Cooper is feeling reckless. He volunteers for the dumbest and most dangerous job going: personal security operations in Afghanistan protecting bent politicians.
But when his principal is killed in a suicide bomb attack, Cooper is reassigned to a cushy job nursing a couple of needy African-American entertainers putting on a show for US military advisors at a secret base in Rwanda.
Or so he thinks.
Things go horribly wrong when their United Nations chopper is forced down in the Democratic Republic of Congo in the middle of an all-out firefight by opposing forces. The nightmare only intensifies when some of Cooper's people, including one of the entertainers, are captured.
While risking his life to rescue his principals, Cooper spies a US DoD advisor in the enemy encampment, which is awash with American weaponry. It seems that their forced landing in this inhospitable place was no accident...
