From Crime Reads:
Ah, sibling rivalry…something anyone with a brother or sister is likely to understand. The arguments, the jealousy, and in my case at least, the hastily scribbled not-so-nice notes shoved under my older sister’s bedroom door when I was eight. While many of us thankfully grow closer to our siblings as we get older and wiser, it’s no surprise past experiences are fuel for the writer’s imagination, allowing us to tread the darker paths (hopefully) never taken. Mysteries and psychological thrillers are perfect for creating and exploring these twisted relationships. After all, a character’s deeply rooted animosity can fester for decades before exploding and unleashing all kinds of evil wrath on their unsuspecting family members. Here’s a list of ten older, more recent and new sibling stories to take you on a wild ride.
We Have Always Lived in the Castle by Shirley Jackson (September 1962)
Mary Katherine “Merricat” Blackwood is eighteen and lives in a big house on large grounds with her older sister Constance, and their wheelchair-bound Uncle Julian. Six years prior, Merricat’s parents, aunt and younger brother died after they were poisoned, and young Constance was suspected of killing them. But did she do it? And how do the surviving family members cope with the increasingly hostile villagers who’d rather see them all burn? This was Jackson’s final work before she died in 1965, age 48.

My Sister the Serial Killer by Oyinkan Braithwaite (Doubleday, November 2018)
The title alone of this book had me clambering for a copy. Korede’s sister, Ayoola, has a habit of, uh, “dispatching” boyfriends, and alleging self-defense. Korede knows it’s anything but. Now Korede’s expected to help clear up another of her sister’s messes instead of going straight to the police, and she helps Ayoola because she loves her… But what will happen when Ayoola starts dating the doctor Korede’s been in love with for quite some time? What will Korede do and who will she choose to save? Wholly original and utterly surprising.
