๐Ÿ”ช Sororicidal Review: Sisterhood… but Make It Psychological Warfare ⭐⭐☆☆☆

⚠️ Trigger Warnings

  • Sexual content (including early experimentation)

  • Animal death

  • Toxic family dynamics

  • Psychological cruelty


๐Ÿ‘€ Why I Picked This Up

I’ve always been fascinated by sibling relationships—probably because I don’t have one. I’m an only child, so I’ll never fully understand that dynamic… but I do see it play out through my daughters.

They’re about two years apart. They love each other. They also occasionally act like tiny rivals in a lifelong competition no one signed up for ๐Ÿ˜…

So when I saw Sororicidal—a story about two sisters who are complete opposites and low-key at war—I was immediately intrigued.

And honestly? It started off feeling very real…

…but somewhere along the way, it lost me.


๐Ÿšจ Spoiler Warning – Full Plot & Ending ๐Ÿšจ


๐Ÿ“– Plot Summary (FULL SPOILERS)

Sororicidal follows Mary and Margot Cussens, two sisters growing up in Edwardian Adelaide, and later into adulthood and old age.

๐Ÿง’ Part One – Margot (Childhood)

Margot, the younger sister, grows up under the shadow of Mary—who is basically a master manipulator in pigtails.

  • Mary commits small, cruel acts that no one ever witnesses

  • Margot has a “wobbly foot,” making her physically vulnerable

  • The sisters create a secret world (Ruby Hedge) and a deeply unhinged “Hate Book” full of people they despise

  • Mary pressures Margot into disturbing rituals (including a literal blood ritual… because why not escalate early ๐Ÿ˜ฌ)

Margot begins forming her own identity through a friendship with Nessy (daughter of the family cook), which includes early sexual exploration—but that relationship collapses after the Hate Book betrayal.

Meanwhile, Mary uses Margot as a subject for her art… and leverages that into her escape from home.

๐Ÿ‘‰ Already, the dynamic is clear: Mary dominates, Margot internalizes.


๐ŸŽจ Part Two – Mary (Adulthood)

Mary returns years later after living in Europe.

  • She reveals she never went to art school initially—she actually left for an illegal abortion arranged by her father

  • Margot is now married with a daughter (Christina), living a quiet, conventional life

  • Mary basically inserts herself into Margot’s home like an emotionally disruptive houseguest

Tensions escalate:

  • Mary paints a nude portrait of Christina (๐Ÿšฉ๐Ÿšฉ๐Ÿšฉ)

  • Margot openly says: “I hate you” (honestly, fair)

  • Mary’s beloved dog, Pip, is poisoned in Margot’s garden

๐Ÿ‘‰ This is where things shift from passive-aggressive to… actively destructive


๐Ÿงถ Part Three – Margot (Later Years)

Now older, the sisters live together again in their decaying family home.

  • Margot finds brief emotional connection with Pamela, a midwife

  • Christina (the next generation) struggles in her own marriage but ultimately chooses independence

  • Margot tries—desperately—to hold onto connection, even physically restraining Pamela from leaving

๐Ÿ‘‰ This section explores loneliness, aging, and generational cycles


๐Ÿ”ฅ Part Four – Mary (Final Years)

Mary is now an elderly artist living part-time in France.

  • She continues manipulating identity through art (literally painting over people’s faces… subtle ๐Ÿ™ƒ)

  • Returns home to find Margot deteriorating physically

And then…

๐Ÿ’ฅ THE ENDING:

  • Margot sets fire to Mary’s studio

  • Instead of reacting with rage, Mary calmly helps contain the fire

  • The sisters sit together… watching the destruction

๐Ÿ‘‰ Not reconciliation. Not forgiveness.
๐Ÿ‘‰ Just… acceptance through mutual ruin


๐Ÿง  Themes & What It’s Trying to Say

  • Sisterhood as both mirror and weapon

  • Identity shaped (and distorted) by others

  • Family as an “unendurable entanglement”

  • Love and cruelty existing side-by-side

It’s very literary. Very symbolic. Very… heavy.


๐Ÿค” My Thoughts (a.k.a. Why This Didn’t Work for Me)

I wanted to love this. The premise? Incredible. The psychological tension? Right up my alley.

But here’s the thing…

๐Ÿ‘‰ I just didn’t feel anything by the end.

  • The characters are fascinating… but emotionally distant

  • The story is layered… but not especially engaging

  • The symbolism is strong… but also kind of exhausting

It felt like I was observing something rather than experiencing it.

And for a book about such an intense, intimate relationship? That’s a problem.

Also… I kept waiting for some kind of emotional payoff, revelation, or gut punch.

Instead, I got:

๐Ÿ”ฅ “Well… everything burned. The end.”

Cool cool cool.


๐Ÿ‘ฉ‍๐Ÿ‘ง Personal Connection (and Reality Check)

There were moments that hit close to home:

  • Opposite personalities

  • Sibling tension

  • That subtle competition dynamic

But thankfully…

๐Ÿ‘‰ My kids are not maintaining a hate diary and performing blood rituals in the backyard ๐Ÿ˜…

So yes—similarities end there.


⭐ Final Rating: 2 Stars

  • ⭐ Great concept

  • ⭐ Strong writing style

But…

  • ❌ Emotionally disconnected

  • ❌ No satisfying payoff

  • ❌ Left me feeling… nothing

And that’s the worst crime a book can commit, honestly.


๐Ÿ“š If You Love Dark Family Dynamics, Try These Instead:

  • Sharp Objects by Gillian Flynn

  • The Push by Ashley Audrain

  • We Need to Talk About Kevin by Lionel Shriver

  • The Sisters by Claire Douglas

  • Everything I Never Told You by Celeste Ng


๐Ÿ’ฌ Final Thought

This is one of those books where I completely understand what the author was doing

…I just didn’t enjoy the experience of reading it.

And when it comes to books about emotional devastation?

๐Ÿ‘‰ I’d prefer to actually feel devastated ๐Ÿ˜…
