Everyone has a soul mate. But what do you do when your soul mate would rather give his soul to the demons than be with you? Seventeen-year-old Erin has a problem. Seth has been hers forever, but now an ancient curse is tearing him away. And the demons who invoked it will stop at nothing – even murder – to claim him as their own. How can she win against a curse so binding that it has damned countless others to this same fate – an eternity alone? The answer lies in the past. To find it, Erin and Seth must risk all, travelling back in time to a dangerous world where love is forbidden, and life – and death – hang on a pledge. Follow Erin and Seth as they travel to ancient Shenaya and confront the curse that has plagued their families for millennia. Caught in a war between the Angelic Guardians and the Gefallen, the disembodied dead, they must fight to keep their souls in tact and their love untainted.
