Impossible to put down – a fast paced thriller with twists and turns around every corner. * Patricia Cornwell * 'I honestly inhaled this, couldn’t wait to get back to it. I think it’s Andrea’s best book yet. The twists just kept coming. An unguessable and most thrilling thriller in the plushest surroundings of south county Dublin. I bloody loved it.' * Liz Nugent * 'Warning: Don’t start Such a Nice Girl if you have anything urgent to do… This dark mystery about two mothers and two daughters is pitch perfect, with great characters, a deviously twisting plot and a pace that breaks the speed limit. An all-round stunning thriller from the queen of the tangled web. Such a fabulous read!' * Janice Hallett * What a fantastic novel. A masterclass in twists and turns. It’ll leave your head spinning. Mara remains at the top of her game and I’m here for it. * John Marrs * Andrea Mara is one of a kind, writing with a vice-like grip and plots perfectly designed to speak to our deepest, darkest fears and get under our skin. Clear your calendar: once you start reading Such a Nice Girl, you won't be able to stop. * Jack Jordan * 'I absolutely loved every second of reading this - a complete pleasure from start to finish. Andrea Mara is a genius storyteller. In Such a Nice Girl she puts you right at the heart of a catastrophic situation and turns up the tension until you feel as invested as if the characters' problems were your own. Fast-paced, compelling, twisty and utterly absorbing, this novel will delight her legions of fans.' * Jane Casey * Mothers. Daughters. Killers. Victims. The combinations are deadly in Andrea Mara's clever, clever new thriller, a novel that pits its characters against one another with real invention, real force. It's genuinely involving, too, as an exploration of friendship and parenthood. This is a good one. * A. J. Finn * 'Utterly gripping from the first to the last page. I devoured it! A masterclass in maternal fear and buried secrets.' * Louise O'Neill * Such a Nice Girl is, in my opinion a 'Wow' book - another surefire bestseller for Andrea. I couldn't turn the pages fast enough. So many twists and turns! I had no idea who was telling the truth or who was spinning lies. I felt like I was on a roller coaster ride while reading it. Andrea is brilliant at plotting. A fantastic premise, executed flawlessly. I can see it as a movie! * Patricia Gibney * Such A Nice Girl is a very fine addition to Andrea Mara's ongoing excavation of contemporary parental anxieties. The kids are older in this one, but the stakes couldn't be higher. Privilege is fragile, complacency is punished, and what starts as a tiny crack in a perfect facade widens inexorably to a chasm. In Such A Nice Girl, the pages turn themselves, and Andrea Mara gets better and better. * Catherine Kirwan *
