In “Dark Rival I,” the noose tightens around Stefano Marino’s neck. While Silvio and Franco are off taking care of the Russian problem, mutiny brews in Stefano’s crime family. It soon becomes clear he can trust only one man in his life, but whether he can hold on to Silvio—and what it might cost his marriage—are questions for which he has no answers.In “Dark Rival II,” Silvio returns from his mission. Job done, threat gone, Stefano knows Silvio has no reason to stay. Or so he thought, anyway, until Silvio makes his move. It seems Silvio wants only sex, but Stefano is well aware there’s much, much more on the line. Including Donata, whose suspicions of a mistress in Stefano’s life are uncomfortably close to an even more uncomfortable truth.Hopeless and helpless as his life crumbles down around his head, Stefano gives in to his desires in “Dark Temptation.” He isn’t any closer to understanding Silvio—and he’s farther from Donata than he’s ever been—but at least he’s come to understand his own needs. Now if only he could figure out how to be himself without hurting the ones he loves the most.
