A standalone adventure in Martin Widmark’s delightfully spooky series about monster agent Nelly Rapp!

When Nelly and Valle join LENA-SLEVA and Uncle Hannibal at the library for a talk about the Viking Age, they have no idea the evening will end in complete chaos. Books suddenly fly through the air, and a chilling laugh echoes between the shelves. And what is going on with Gunlög, the grumpy librarian? She seems to be hiding something.

To find out what’s happening, Nelly and Valle must use the help of the three C’s: calmness, cleverness and cunning. But will that be enough when forces from the Viking Age are unleashed …?

An exciting, funny story with just the right amount of spookiness for beginner readers. Nelly Rapp and the Poltergeist is the twenty-seventh stand-alone book in Martin Widmark’s cozy series about monster agent Nelly Rapp, with vibrant color illustrations full of humor by Mattias Andersson.
