Sororicidal presents a gothic-punk exploration of sisterhood, focusing on the intense bond between Mary and Margot, which oscillates between devotion and destruction. As they transition from childhood to adulthood, Mary pursues an artistic, bohemian lifestyle abroad, while Margot opts for the conventional path of marriage and motherhood. Despite their diverging lives, they remain inextricably linked by love and rivalry, facing betrayal, love affairs, and war. Their relationship is continually tested, embodying both mirrors and adversaries. The novel delves into the complex dynamics of family, the weight of expectations, and the fine line between care and ruin, showing how profound love can shape, devastate, and ultimately consume. It paints a vivid, intense portrait of how sisters remain interconnected throughout life as both support and sabotage for each other�s desires. Geordie Williamson has described this book as �Ferrante but set in early Twentieth century Adelaide, with a gothic twist.�.
