Sixteen-year-old Juliet Moreau has built a life for herself in London-working as a maid, attending church on Sundays, and trying not to think about 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 is alive and continuing his work on a remote tropical island, she is determined to find out if the accusations are true. Accompanied by her father's handsome young assistant, Montgomery, and an enigmatic castaway, Edward-both of whom she is deeply drawn to-Juliet travels to the island, only to discover the depths of her father's madness: He has experimented on animals so that they resemble, speak, and behave as humans. And worse, one of the creatures has turned violent and is killing the island's inhabitants. 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. Inspired by H. G. Wells's classicThe Island of Dr. Moreau,The Madman's Daughteris a dark and breathless Gothic thriller about the secrets we'll do anything to know and the truths we'll go to any lengths to protect.
