Katherine Langrish's Troll Mill

Set three years later.  The family's settled in with Peer as one of them.  Now that he's older, he's developing feelings for the lovely Hilde who's always been by and on his side.  Peer just wants to be grown and show how independent and self sufficient that he is to Hilde.  Then, the dilemma of the story.  Kersten, Bjorn's wife, runs at Peer with her baby and tells him to bring it to Bjorn.  She runs off into the water and then the book starts to move.
