Truly marvellous! As compelling as it is stylish, SISTER exists in that rare place where crime fiction and literature coincide.
Fast-paced and absurdly entertaining . . . Along with a juicy mystery, it resounds with an authentic sense of sisterly love and loyalty.
Beautifully written - you believe every word.
Lupton's crisp insights into grief and familial guilt are married to a confidently executed plot. Free from the genre's more mawkish excesses, Lupton's persuasive narrative voice is what keeps this classy debut on track.
A psychological murder mystery written with literary flair . . . Be prepared for page-turning.
This superb debut novel has so many twists and turns as to cause dizziness - it's the literary equivalent of 'scream if you want to go faster' - and just when you think things are slowing down to a peaceful, settled resolution, there's one more stomach-churning final turn in store.
Tense, gripping and a total page-turner.
A chilling, gripping, tragic, heart-warming, life-affirming enigma of a story.
A heart-tugging, tense mystery . . . It is very good.
With SISTER, Lupton enters the highly charged ring where the best psychological detective writers spar, her hands raised in a victory clench. Like Kate Atkinson, Patricia Highsmith and Ruth Rendell, Lupton builds suspense not only around the causes and details of her story's brutal denouement, but also around the personalities . . . Both tear-jerking and spine-tingling, SISTER provides an adrenaline rush that could cause a chill on the sunniest afternoon.
Lupton's classy debut is a welcome and exciting addition to the genre.
Original, spooky and clever, this thriller is utterly compelling.
This sophisticated psychological thriller is brilliantly written and utterly gripping.
Nicci French via Ford Madox Ford, anyone? Lupton's debut is an exceptionally confident domestic gothic thriller...it also packs a devastating punch.
Stunningly accomplished from first page to last, this is the most exciting debut thriller I've read all year. The suspense crackles, and the twists come thick and fast, but more than that it has a touching poignancy that brings tears to your eyes . . .Written with the power and panache of a young Daphne du Maurier, it s devastatingly good, and announces the arrival if a truly original talent.
