Sister of Mine by Laurie Petrou is a 2018 Crooked Lane publication.
A sister can be seen as someone who is both ourselves and very much not ourselves- a special kind of double. -Toni Morrison
This book explores a much more complicated sisterly relationship than most, which creates a taut, atmospheric environment, with tension building and building, finally reaching a riveting breaking point.
Penny’s husband becomes abusive which, in total desperation, causes her to pull her younger sister, Hattie, into a scheme to rid herself of him before he kills her.
While it appears as though their plan has gone off without a hitch, the relief they are expecting never materialized. Instead, they have traded one unbearable situation for another, as the dynamic between the sisters begins to shift, slowly at first, but becoming more pronounced as time passes. However, as sisters, they are bound together by their terrible secret.
But, when a private investigator takes an interest in the case the tension becomes even more miserable. In addition, Hattie tries to move on with her life by marrying and trying to start her own family, which creates an atmosphere akin to a pressure cooker.
Will Penny and Hattie ever find peace? Will their sins finally catch up with them?
This book is marketed as a domestic thriller. It does fit into that category, but not in the traditional sense. There is a crime, but we know, beginning with the first chapter, who is murdered, why, and how. The suspense comes from the aftermath, and it’s not so much a cat and mouse game, although that element does factor in, but the sense of foreboding that hangs in the air, that feeling that something is about to implode or explode, and when it does, it won’t be pretty.
In some ways this book is an interesting character study as well as a complex exploration of sisterly bonds and duty, which can be as mysterious and complex as the mother/daughter relationship.
The rivalry is paralleled by the sacrifices one makes for the other, and the loyalty that was once more freely given, that is now forced.
It’s a strange, almost claustrophobic feeling at times, but the author did an amazing job at developing the suspense with precision timing and pacing. Once all is said and done, it seems to me this novel defies classification. The story is as much of a family drama as it is a thriller. The 'for fans of' Liane Moriarity comparison is a bit of a stretch, in my opinion, but, overall, this is a nice, fresh, and original debut novel.
I appreciated the unique take on sisterhood, and the interesting approach to the domestic thriller trope. This was quick and easy read for me, but it took me by surprise, in a good way.
This is an author I’d like to hear from again.
