H. G. Wells 
The Island of Doctor Moreau 

Written in the Victorian era, this book since then has been an inspiration for many sci-fi movies and books that are now published. The main themes of the novel are the dangers of scientific hubris and the dividing line between the human and the animal. The book was first met with atrocious revolts from the readers as rising the concept of blasphemy; but the more time has passed, the more readers have felt compelled in continuing with it. The Island of Doctor Moreau is often defined as a page-turner, stomach-churner, and one that gives its readers nightmares. This short novel takes on some big philosophical and moral questions such as the use of vivisection in the pursuit of knowledge, which is still hot-button issues today.
