Also generating huge interest is the final installment of Elena Ferrante's Neapolitan tetralogy: The Story of the Lost Child (Europa Editions, Sept. 1, $18, 480 pages). The series about the friendship between two women in Naples, Italy, from the 1950s to the present, has been something of a literary Breaking Bad, starting off with a lowish profile and picking up passionate fans as it's gone along. Adding to the hype is the mystery surrounding the identity of the author, who refuses to reveal her or his real name (Ferrante is a nom de plume) and only does interviews via email.
