chunk: Sections of Jo's Boys follow the travels of former students who have deep emotional ties to Plumfield and the Bhaers. Professor Bhaer's nephew Emil is now a sailor, and takes off on his first voyage as second mate and shows his true strength when he is shipwrecked and the captain badly injured. Dan seeks his fortune in the West and ends up in jail. He also falls in love with a person far beyond his reach, Jo's niece and Amy's daughter Bess. Nat begins a musical career in Europe that takes him away from Daisy, only to fall in with a frivolous crowd and unintentionally lead a young woman on, whom he then does not marry.
  Romance also plays a role in Jo's Boys, as both Franz and Emil find their own wives, and Tommy, Demi, Nat and Daisy are engaged by the end of the book. Nan remains single, dedicated to her medical career.
