The Good Sister by Sally Hepworth

Sally Hepworth, the author of The Mother-In-Law delivers a knock-out of a novel about the lies that bind two sisters in The Good Sister.
There’s only been one time that Rose couldn’t stop me from doing the wrong thing and that was a mistake that will haunt me for the rest of my life.
Fern Castle works in her local library. She has dinner with her twin sister Rose three nights a week. And she avoids crowds, bright lights and loud noises as much as possible. Fern has a carefully structured life and disrupting her routine can be…dangerous.
When Rose discovers that she cannot get pregnant, Fern sees her chance to pay her sister back for everything Rose has done for her. Fern can have a baby for Rose. She just needs to find a father. Simple.
Fern’s mission will shake the foundations of the life she has carefully built for herself and stir up dark secrets from the past, in this quirky, rich and shocking story of what families keep hidden.

The Reason
I have enjoyed Sally Hepworth’s books in the past and this one sounded good.
The Quotes
“The library belongs to everyone. The library, Janet used to say, is one of only a few places in the world that one doesn’t need to believe anything or buy anything to come inside.”
“I’d always found there was something agreeable about people who liked dogs and something untrustworthy about those who didn’t.”
“If it were up to me, every child would have a year in the library before they went to school.”
“Sisterly relationships are so strange in this way. The way I can be mad at Rose but still want to please her. Be terrified of her and also want to run to her. Hate her and love her, both at the same time. Maybe when it comes to sisters, boundaries are always a little bit blurry. Blurred boundaries, I think, are what sisters do best.”
The Narrator(s)
Barrie Kreinik. She was overall good, but there were times when her voices for each character was inconsistent and I wasn’t sure who was talking.
My Thoughts
This is one of the best mystery thrillers I’ve read in a while. I was so incredibly invested in the story and it really felt like I had my heart in my throat for most of the second half of the book. The first half was also very interesting because Fern’s POV read like a wholesome romance, while Rose’s POV was so sad and difficult to read at times.
I did figure out early on what was happening, but it didn’t ruin the story for me because the journey from beginning to the end was just so good. These are some of the most interesting characters I’ve come across and I especially love Wally/Rocco’s character. To be clear, some of these characters aren’t necessarily good people and I do question some of their actions, but they are so interesting to read about and get to know as we move through the book.
It’s early in the year and I already feel like this may be one of my favorite books this year. I would be very happy to be proven wrong because that only means that I’ll have many more great books to look forward to, but this one was just incredible.
