Operation Blue Dragon — Stephen Dando-Collins

Second in the series, Caesar is back on duty and in Afghanistan for his most daring mission yet

When SAS hero Charlie masters his prosthetic legs and proves his superiors wrong when they say his fighting days are over, he returns to SAS service -- and gives Caesar the super-sniffing Explosive Detection Dog back to Ben, his trainer. On their first mission after they're reunited, Caesar and Ben discover a bomb at the Sydney Opera House, targeted at the visiting Secretary General of the United Nations. A little later, the Secretary General's helicopter goes down while touring Afghanistan, and he is captured by the Taliban's Commander Baradar. Along with their friends Duke Hazard and Sergeant Tim McHenry from the U.S., Caesar, Ben, and Charlie form the team sent in to rescue the Secretary General from a cave beside Afghanistan's Dragon Lake. How will they succeed? An experimental mini submarine will help -- and Caesar's famous nose is sure to sniff out trouble along the way.
