The cruel Duke Rowan Alexei Peruka is a lovestruck puppy around Erin — all thanks to a random magic spell that was cast just as he was about to execute her. But with the spell’s power now waning and on the fritz, his shifting moods zip from dramatic professions of eternal love to cold threats of death. Exhausted from the emotional whiplash, Erin must find a magic spell to not only save herself but also her enchanting fairytale marriage before she loses her beloved and bewitched “Ru” forever.
