Recommended as a satisfying conclusion to a trilogy.  If you’re going to purchase this for your library, you’ll want to get the first two books, How to Catch a Bogle, and A Plague of Bogles, too.  Each book does provide enough context individually so that if a student picks them up out of order they will still make sense.  Set in the streets of England in the days before there were social services available to look after children on their own, these books tell the tales  of street kids who make their way in the world as assistants to a Bogle Hunter, working to clear the sewers and basements of London of the child-snatching bogles terrorizing the town.  It’s dangerous work, and the books are descriptive enough to offer a few goosebumps, but not overly done in the gruesome department.
