Tohtori Proktorin aika-amme

This was epic. I think this is even better than the first book in the series. The book is a bit heavy on the history, considering it's for children, but my son quite liked it, as he's a bit of a history buff. Anyway, the story was interesting, full of twists and turns and rather odd bits of humour. There's real drama and emotion, as well. Jo Nesbø is quite the genius, both in his books for adults and for children. Highly recommended!
