Alastor isn't keen to be banished back to the demon realm and will do anything to try and trick his unwilling host into a contract - from nasty insults to wild promises. And even more unnerving, his power over Prosper seems to be growing with each passing night.
Prosper has only days to break the curse - a feat that seems impossible. But with the help of a feisty witch-in-training, maybe he can do it?
