Series numeration from Fantastic Fiction.

Pike Logan and Jennifer Cahill are enjoying a sunny vacation down under when they get disturbing news: their friend and colleague Clifford Delmonty is in serious trouble. While working as a contractor at an Australian F-35 facility, the former Taskforce member--callsign Dunkin--saw something he shouldn't have, and now he's on the run from Chinese agents. Pike and Jennifer soon discover that Dunkin's attackers are a dangerous link to a much larger scheme that could launch a full-on conflict between China and Taiwan. In its quest for dominance, China is determined to reclaim Taiwan--a pivotal ally the United States has sworn to protect. Pike learns that the Chinese have a devious plan to bait the island nation into all-out war by destabilizing the government and manipulating an artificial intelligence defense system. As the threat reaches a boiling point, Pike alone realizes that what they're seeing isn't actually real. A soldier who has always been trained to fight and win, Pike must now track down and neutralize the missing man who holds the key. With the help of Jennifer, the Taskforce team, and a brave Taiwanese intelligence agent, he races to prevent a catastrophic conflict from consuming a whole region of the world. -- from book jacket.
