Synopsis according to Goodreads:
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 classic The Island of Dr. Moreau, The Madman’s Daughter is 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.“
I highly recommend this book for lovers of classic gothic stories, strong female protagonists, well-executed historical fiction, fans of science and the classic themes of science fiction, and those who enjoy believable romances and surprises.
