Sabrina knows there's a way to get Nick back while also keeping dear old dad out of commission. She just has to figure out what it is. Unfortunately, her loyal cousin Ambrose is unavailable as he's off hunting Father Blackwood, the evil former head of the Church of Night. Fortunately, Sabrina's still got her mortal friends, Roz, Harvey and Theo. So when her aunt Zelda – now the church's high priestess – mentions an ancient quest that might help open the gates of Hell, Sabrina and her friends are all in. But Zelda failed to mention that the quest has some perils of its own.
