This is an awesome series that I have been reading that centres on Peter Grant, an officer in the Metropolitan police of London, who after a strange encounter with a ghost, joins a part of the force that deals with the supernatural and becomes the first apprentice wizard of the force in 70 years. Diana Gabaldon claimed this is "what would happen if Harry Potter grew up and joined the Fuzz."
Through the books, he is learning to become a wizard as well as solve crimes and learn about what there is in the supernatural world. It is great British humour.
The books do touch on themes of sex and alcohol and such but don't shy away from letting people read them. They could start some good conversations but the themes aren't so prevalent that they will. If students are already reading series' such as Mortal Instruments or Steven King books, I think these are okay.
