The book being reviewed today, a tense, deftly written novel about an apparently perfect nanny’s transition into a monster, will take your breath away. It's called Lullaby and it's an English translation of a book by the French writer Leila Slimani. Our book clubbers Roisin Ingle, Bernice Harrison and Niamh Towey were totally freaked out by Lullaby and might not recommend it to parents of young children, but all agreed it was an absorbing read and one that stays with you long after you've put it down for the last time.

Next time on the book club: Edna O'Brien's The Country Girls.
