Pre-release readers are calling it intoxicating, fierce, and sinister:
Taylor Jenkins Reid, the New York Times bestselling author, said she wants this book fed directly into her veins.
Lucy Rose, author of The Lamb, called it a darkly intoxicating and fierce sapphic retelling of Hamlet, full of longing, rage, and grief.
Jennifer Saint, author of Ariadne, described a sinister story shot through with beautiful, delicate sapphic yearning.
Library Journal, in a starred review, praised it as a feminist retelling that pairs sensual storytelling with tragic consequences.
