Code Name Sonny (Unabridged‪)‬

Joe got his wish in the spring of 1944. In Code Name Sonny, author Ken Pottie takes readers on a thrilling journey, zigzagging back and forth between Sonny's World War II experiences and Jack's modern day investigation into his dad's war service, as the latter tries to unravel mysteries by tying together pieces of historical recollection with current news stories. 

When the past and the present collide, Jack realizes too late the danger lurking close to home.
