Sixteen-year-old Juliet Moreau has built a life for herself in London-working as a maid and trying to forget the scandal that ruined her life. After all, no one ever proved the rumors about her father''s gruesome experiments. But when she learns he''s alive and continuing his work on a remote tropical island, she''s determined to find out if the accusations are true.
Accompanied by her father''s handsome young assistant, Montgomery, and an enigmatic castaway, Edward, Juliet travels to the island, only to discover the secret of her father''s new life: He experiments on animals so that they resemble, speak, and behave as humans. Torn between horror and scientific curiosity, Juliet knows she must end her father''s dangerous experiments and escape her jungle prison before it''s too late. Yet as the island falls into chaos, she discovers the extent of her father''s genius-and madness-in her own blood.
