Briseis holds a gift both wondrous and perilous: she can coax plants to life with a mere touch. It's a secret ability she's been shielded from flaunting, until inheriting a house from her birth mother upends her life. As Briseis nurtures the garden, it blooms with not just flora, but layers of familial mystery and the legacy of a dark goddess. At the heart of this overgrowth lies a collection of deadly plants, the Poison Garden, and the call of her ancestors, urging her to embrace a witch's heritage. 'This Poison Heart' by Kalynn Bayron, the author of 'Cinderella Is Dead', is a tale of identity and a young woman's journey to reconcile her power with her place in the world and the tangled roots of her past. The pursuit of her destiny unfolds against a modern tapestry woven with threads of Greek mythology and the enigmatic lore of witchcraft.
