The Doodlebug War: a Tale of Fanatics and Romantics in Bloomington, MN

The time is the immediate future, and the Caliphate is the enemy in the third Frank Adversego Thriller. Mullah Muhammed Foobar, the mysterious leader of a post-ISIS terrorist organization, has won control of much of the Mid East. Now he threatens to launch a horrific attack that will bring the United States and Europe to their knees.
But How? The CIA turns to cybersecurity super sleuth Frank Adversego to find the answer. In a race against time, Frank must overcome personal as well as cyber trials to save the Western world from destruction. When he does, he discovers an all-too-real vulnerability that may lead to our own downfall - not at some theoretical point in the future, but as soon as tomorrow.
In the words of "world's greatest hacker" Kevin Mitnick:
Andrew Updegrove has done it again - delivered an impossible to put down thriller while exposing a dire cyber vulnerability that until now has gone unnoticed.
