Summoned to her father's Philadelphia house in 1826 after her mother's death, seventeen year-old Annabel Lee's whole life is about to change. Here, she can't wear pants and practice medicine like she used to in Siam. The new city she's supposed to call home is full of dark secrets and strange curiosities—a world she has trouble navigating.
Until she meets her father's assistants.
There is Allan—darkly handsome and gentle natured, he dabbles in writing stories when he's not helping with medical advancements in her father's laboratory, and Edgar—who bears an uncanny resemblance to Allan, but is everything Allan is not. Cruel, selfish, and determined to see his own gruesome fantasies brought to life.
When her brilliant, but reckless, father's scientific experiments rapidly morph into morbid obsession, a terrible truth is revealed: Edgar and Allan are two halves of the same person, and Annabel quickly finds that her own attempts to cure Allan of his "affliction" are becoming as morally questionable as her father's.
But nothing can prepare her for the lengths she'll have to go to when her father is kidnapped by the dangerous and mysterious Dorian Gray in his relentless pursuit for the ultimate scientific breakthrough—eternal life. To hunt for a monster, Annabel will need a monster, and she is forced to unite with Edgar to save her father—the man responsible for creating them both.
