The Light in the Ruins (Vintage Contemporaries)

1943: Tucked away in the idyllic hills of Tuscany, the Rosatis, an Italian family of noble lineage, believe that the walls of their ancient villa will keep them safe from the war raging across Europe. But when two soldiers—a German and an Italian—arrive at their doorstep asking to see an ancient Etruscan burial site, the Rosatis’ bucolic tranquility is shattered.
 
1955: Serafina Bettini, an investigator with the Florence Police Department, has successfully hidden her tragic scars from WWII, at least until she’s assigned to a gruesome new case—a serial killer who is targeting the remaining members of the Rosati family one by one. Soon, she will find herself digging into past secrets that will reveal a breathtaking story of moral paradox, human frailty, and the mysterious ways of the heart.
