npr.org – The daily lowdown on books, publishing, and the occasional author behaving badly. i Say one thing about Jonathan Franzen: He doesn’t shy from an ambitious book title. Fresh off Freedom in 2010, Franzen plans to release a new novel next September — the modestly titled Purity. The novel, Franzen’s fifth, appears to be no less ambitious in its content. Focused on a character named Purity Tyler, a woman on the hunt for her father’s identity, the book is likely to be something of a sprawl, covering multiple generations and continents in its exploration of family.
