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 * 'Utterly gripping from the first to the last page. I devoured it! A masterclass in maternal fear and buried secrets.' * Louise O'Neill * 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 * Praise for Andrea Mara * : * Andrea Mara is a star. * Lee Child * I was hooked from first page to last as the twists got twistier and all of the characters squirmed while waiting for their darkest secrets to be revealed. May I suggest a new Irish blessing? May you never live in a neighbourhood created by Andrea Mara. * Liz Nugent * Ingenious plotting, brilliantly written, pacy and totally unpredictable, I devoured it over a weekend...Absolutely outstanding! * Claire Douglas * This heart-thumpingly tense thriller may give you nightmares. * Sun * Mara... lays out the pieces of the puzzle with diabolical wit, some good suspense and an unexpected note of sentimentality. * New York Times * This one is an absolute page turner! * Shari Lapena *
