Synopsis – The Quiet Sister
Keep your enemies close… your sister closer 🩸 Pulse-pounding thriller for fans of Sue Watson, Shalini Boland and Freida McFadden!
To outsiders, twins Mia and Chloe have always been close, like good sisters should be. But in private their relationship is one of jealousy, resentment and bitterness.
Popular and attractive Mia is always the centre of attention, loved by all. Quiet and reserved, Chloe is overlooked and underestimated, and has tried to build a life away from Mia and her manipulation. Finally she is happy and content.
But then Mia returns and makes it clear that she wants to be part of her sister’s life again, to have everything Chloe has…including her new fiancé Scott.
Chloe can’t allow Mia to ruin her life again. She’s done this too many times in the past – always taking things that don’t belong to her.
As old tensions, secrets and lies return, tragedy strikes. And one sister will use the opportunity to live the life she has always wanted…the life she has always deserved.

My Review
The Quiet Sister: A BRAND NEW utterly chilling psychological thriller from bestseller Alex Stone for 2025 by Alex Stone
My rating: 3 of 5 stars
The premise of this book was interesting and engaging. Twins who struggled to connect and always competing. Neither twin was very likable. One was manipulative and the other was whiny.
The story is told in alternating time lines – then and now with some additional flashbacks much further into the past.
I do think it was too long and so parts felt repetitive. With some editing and removing length I think this would have made the story more engaging. The story did not feel particularly twisty to me.
I think there were other things that could have been delved into more deeply to have made the story that much more engaging, lots left unexplored about the relationship between the sisters.
Despite the issues with the story, it was one that I wanted to keep reading because I did want to see how it turned out.
Overall, I think if you like psychological thrillers you should give this one a try for yourself. It didn’t quite connect with me, but I can see how it would appeal to many readers.
