Offspring by Jonathan Strong

Lloyd Schwartz recommends
Offspring, a novel by Jonathan Strong (Zoland): "Reading a novel by Jonathan Strong is like finding a secret treasure in a dark attic. 'Every unhappy family,' Tolstoy wrote, 'is unhappy in its own way.'
Offspring is the tale of a peculiarly happy family that lives in an unhappy world which can't understand-or stand-their happiness. Disturbing, haunting, and very moving, this book kept me awake long after I finished it. I'd call it a masterpiece."
