She's proven wrong when Regan reappears and forces her and her friends into the dangerous maze he created.
There's only one rule: they have twenty-four hours to escape, or they'll be imprisoned in his Nightmare realm forever. Stronger than before, it quickly becomes obvious Regan has some sinister new tricks up his sleeve as they encounter the horrors lurking within the maze.
When it's revealed only someone with magic could have set Regan free, the coven begins to splinter, and Avery soon realizes that keeping the coven together might prove more difficult than escaping Regan's world.
