After Midnight

Twenty years later, Lindy Carr arrives in Italy to find out what happened to her father. Her guide is Jack Kirby, a daredevil motorcycle racer and pilot who flew Mosquito fighters in the war and spent time among the Italian partisans. Jack knows the region where Bill Carr vanished like his own backyard, and the farther he and Lindy push into the mountains, the more convinced he becomes that he knows something about the fatal flight in question as well. What Jack and Lindy uncover in the picturesque Italian Alps is a secret so earth shattering it will change both their lives forever.
After Midnight is the 1st book in the Post-War Trilogy, which also includes Last Sunrise and Dying Day.
