Mike Doyle wasn't in Belvidere on April 21, 1967. The Rockford native was a freshman at UW-Whitewater when an F4 tornado ripped through Boone County.
But Doyle's been living with that twister for years.
His book, The Belvidere Tornado, was first published in 2008. It tells the stories of people who survived the storm, and the 24 who didn't.
When Doyle finished the manuscript, he got up from his desk and walked into the living room.
