Erin Hamilton and Dante Gabriel are living together and are more in love than ever, but the mysteries surrounding them continue to evolve. When two more women go missing—Dante's sister and Erin's best friend—they dive in more deeply, recruiting Erin's brother to help.

Despite his quest for information, Dante resists falling prey to his former captor's drive to control his mind. As more changes reveal themselves, he relies on his own strength and his love for Erin to keep himself in check. But the darkness following him is determined to manifest, and its source is a surprise to all.
