'Lalla Rook is ruthless, unapologetic and shamelessly murderous, you're going to love her' Gillian McAllister ‘A wickedly dark and hilarious debut … witty, wise and wildly entertaining’ Alice Feeney 'Deliciously dark, clever satire. Lalla Rook is a genius creation. I absolutely loved it!' Shari Lapena - There’s a dead body in my living room. I’ve not called the police because it was I who stabbed him. Seven times in all. The truth is, it’s surprisingly difficult to dispatch someone with a vegetable knife. In case you’re wondering, the dead man is not my husband. I do resent our pitiful sex life and his woeful lack of ambition, but I wouldn’t murder him for it. Not yet, anyway. Right now, I have far more pressing concerns: scheming to get my daughter into the perfect school; buying my dream home in Hampstead; and disposing of a corpse. A woman’s work is never done. I’ve created the perfect life – and I’ll kill to keep it.

J. Finn ‘Big Little Lies meets Dr. Jekyll and Mr. Hyde’ Booklist ‘A blackly comic delight … sharply sardonic and unputdownable’ Financial Times ‘A witty, propulsive debut with an anti-hero you can't help but root for’ Mirror ‘Hilariously dark, refreshingly honest, and highly entertaining’ Woman’s Weekly READERS LOVE LALLA ROOK ‘This one is a wild ride, but in the best way possible … What a main character!!!!’ ????? ‘Perfection to read … such a good ride’ ????? ‘An incredibly fun read!
