Rosy and Amy are two sisters, bound by a dark childhood secret that has the power to tear their family apart. The sisters have grown apart, with Amy living in a psychiatric home, never having recovered from the night their father left. Meanwhile, Rosy is trying to move forward with her life, whilst living in fear that Amy might reveal the truth about their past.
Amy confides in new psychiatrist James, who is intrigued by what she is hiding from him. Wanting answers, he asks to speak to Rosy to better understand the past the sisters share, but he quickly senses that the sisters are covering something, what unfolds will blow your mind.
I am always so excited to read a new book by the ‘Queen of Thrillers’, Jane Corry, and this latest one certainly didn’t disappoint. The plot is fast paced, twist-laden, and full of suspense. Just when you think you have worked it out, Corry delivers another unexpected turn. The unpredictability of the storyline kept me constantly guessing, with so many unexpected twists and turns.
The novel explores themes including rivalry, misogyny, mental health, generational trauma and the lasting damage of family secrets, adding emotional depth beneath the surface tension of the mystery.
Overall, this was a gripping thriller which I struggled to put down.
