In Dublin in 1878, witty and beautiful Florence Balcombe weds rising theatre manager and aspiring novelist Bram Stoker, putting behind her modest origins and an engagement to Oscar Wilde that ended without explanation.
Once settled in London, she charms the literary, theatrical, and artistic worlds with dazzling salons, while Bram runs the Lyceum Theatre for Henry Irving, the age's most celebrated actor.
The glittering surface conceals a husband enslaved to Irving's narcissistic demands and a marriage bed grown noticeably cold.
Oscar's trial for gross indecency leaves Florence terrified for her family, for a secret she will not name, and for a fanged demon that pursues her through daylight and darkness.
Even her considerable gifts cannot keep the vampire Dracula, her husband's creation, from swallowing the light around her.
She will battle every living threat and every phantom that stalks her, though the cost may be her own mind.
