Sabina Mancari never questioned her life as the daughter of Chicago's leading mob boss until bullets tear apart her world and the man she thought she loved turns out to be an undercover Prohibition agent. Ambushes, bribes, murder, prostitution—all her life, her father sheltered her from his crimes, but now she can no longer turn away from the truth. Maybe Lorenzo, the fiance who barely paid her any attention in the last two years, has the right idea by planning to escape their world. But can she truly turn her back on her family?

All his life, Lorenzo's family assumed he would become a priest, but he has different ideas—marrying Sabina and pursuing a career in the law. Despite his morals, he knows at the core he isn't so unlike his mafiosi father and brothers. Has he, in trying to protect Sabina, forced her into the arms of the Prohibition agent bent on tearing her family apart? How can they rebuild what has so long been neglected and do it in the shadow of the dark empire of the Mafia?

Shadowed Loyalty, set amid the glitz and scandal of the Roaring Twenties, examines what love really means and how we draw lines between family and our own convictions, especially when following one could mean losing the other.
