I would recommend 'The Giver' by Lois Lowry for beginners. It's set in a seemingly utopian society but makes you think about the cost of such a society, like the loss of emotions and memories. 'I, Robot' by Isaac Asimov is also a good choice. It makes you think about the relationship between humans and robots, and the Three Laws of Robotics. And 'Stranger in a Strange Land' by Robert A. Heinlein can be interesting for beginners as it makes you think about different cultures and what it means to be human.
Sure. 'A Wrinkle in Time' by Madeleine L'Engle is very thought - provoking for beginners. It has elements of time travel, different dimensions, and the fight between good and evil, which can really make you think. Also, 'The Island of Doctor Moreau' by H.G. Wells. It makes you think about the ethics of scientific experimentation and the line between human and animal. And 'The Invisible Man' by H.G. Wells too. It makes you think about the power and isolation that invisibility could bring.
