Why would you pretend your life is a dream when you're living a nightmare?

I thought my sister was happy. I thought what we all thought: that Annie and Dom led perfect lives in a lovely cottage in a quiet village by the sea, with flowers at the front gate and an apple tree in the garden. Everyone knew them: generous, loving Dom, creative, joyful Annie.

But I never saw Annie as she sat waiting for Dom well into the night. I didn't see her smiling through her tears. I didn't know what the perfect couple were hiding.

So when sirens break the silence of the night and flames rise against the dark sky, and I get the call I never expected, I'm left with a simple burning question: who was to blame?

A brilliantly twisty tale of family secrets and the darkness that can lie behind closed doors, Her Sister's Secret will keep you turning the pages till the final devastating revelation. Fans of Lisa Jewell, Gillian Flynn and Louise Candlish will love it.

See what everyone's saying about Her Sister's Secret:

'AMAZING... Susie Lynes is the one to blame for the bags under my eyes, for me being unable to focus on work because all I want to do is get back to reading... and for the palpitations in my heart as once again she spun her magical writing web and trapped me inside the pages!... I could feel little fingers of doubt run up and down my spine as I tried to work out who to trust and who not to trust... Perfectly addictive' Chapter in my Life, ⭐⭐⭐⭐⭐
