The Poison Daughter Summary By Chapter | Sheila Masterson
Introduction To The Poison Daughter (Chapter-by-Chapter Summary)
Masterson crafts a gripping tale of political intrigue, resurrected monsters, and deep-seated familial trauma set in a world where the descendants of gods wield magic and the walls of civilization are barely holding back the Drained—creatures born from corrupted blood magic.
When Harlow’s parents arrange her marriage to Henry Havenwood, the heir of a long-lost mountain fortress, she discovers two devastating truths: she already tried to kill Henry in a bar, and he is immune to her poison.
What follows is a dangerous game of spy versus spy, as both families use the marriage as cover for their own agendas.
