Gillian Flynn, The Grownup - book review

The pressure to write the next book after Gone Girl must be immense. Gillian Flynn’s third novel has been extraordinarily successful, selling millions of copies, and it’s easily one of the most talked about novels of recent years. With this stopgap publication Flynn and her publisher have sidestepped that pressure. The Grownup is a short story masquerading as a novella, a story that first appeared last year under a different title, What Do You Do?, in an anthology put together by George R R Martin, and which is now published as a standalone stocking filler.
