Some sins are too delicious to resist. At twenty-one, Seraphina knows she’s going straight to hell. Her crime? Seducing Dominic Ashcroft—her sister’s husband. The magnetic, silver-haired billionaire who’s twice her age and completely off-limits. While Elena fights breast cancer, Seraphina and Dominic are fighting an attraction that’s burning them both alive. Every stolen glance. Every forbidden touch. Every moment they pretend they can resist each other. Dominic tells himself he’s a good man. A faithful husband. But late at night, it’s not his wife he’s thinking about—it’s the temptation sleeping next door. Seraphina doesn’t pretend to be good. She knows exactly what she wants: the one man she can never have.
