Should he recommend some alien sci-fi novels with male protagonists?

A really good alien sci fi novel is 'Alien' by Alan Dean Foster (based on the movie). It delves into the horror of an encounter with a very hostile alien species. 'Starship Troopers' by Robert A. Heinlein also features alien bugs that humanity is at war with. And 'Rendezvous with Rama' by Arthur C. Clarke is a great read. The discovery of the Rama, an alien spacecraft, is full of mystery and scientific speculation.

One of the best is 'Ender's Game' by Orson Scott Card. It features an alien race known as the Buggers. The story follows a young boy, Ender, who is trained to fight against this alien threat. Another great one is 'Dune' by Frank Herbert. It has the sandworms and the Fremen, with complex political and ecological systems involving these alien elements. And 'The War of the Worlds' by H.G. Wells is a classic. It tells of the Martian invasion of Earth, which was very innovative for its time in depicting an alien attack.

One popular sci fi alien novel is 'Ender's Game' by Orson Scott Card. It involves a young boy, Ender, being trained to fight against an alien race known as the Buggers. Another is 'War of the Worlds' by H.G. Wells, which tells the story of a Martian invasion of Earth. 'Dune' by Frank Herbert also features unique alien elements and a complex universe with different species.

A less - known but great 'alien human romance sci fi action' novel is 'A Darkling Plain' by Philip Reeve. It's set in a post - apocalyptic world where humans and strange alien - like creatures interact. The relationships between the human characters and some of these otherworldly beings have elements of romance, and there are plenty of action - filled battles and chases throughout the story.

😋I recommend the following novels to you, all about science fiction and alien civilizations: 1. [The Strongest Interstellar Commander: The story of humanity's counterattack against the entire universe.] 2. The Unsinkable Starship: The story of the sole survivor of an alien spaceship trying to survive. 3. Living on the Computer: The story of a person living on a computer. 4. [Silent Starry Sky Incineration]: It described the story of an invincible expert on Earth who could cross the universe with his physical body and destroy planets with a single punch. 5. [The trump card of dawn: tells the story of the resistance organization after Earth became a colony.] I hope you like this fairy's recommendation. Muah ~😗

Another one is 'Brown Girl in the Ring' also by Nnedi Okorafor. It's set in a future Toronto where the rich have fled the city. The story centers around a young black girl, Ti - Jeanne, who has to face various challenges and dark forces with her special powers. It's a blend of Caribbean and African mythology in a sci - fi setting.

Some of the best new alien sci - fi novels include 'The Three - Body Problem' by Liu Cixin. It presents a fascinating view of an alien civilization's interaction with Earth. Another one could be 'Ancillary Justice' by Ann Leckie, which features unique alien cultures and complex galactic politics. Also, 'Children of Time' by Adrian Tchaikovsky is great. It tells a story about the evolution of spiders on a planet and their relationship with humans.

Arthur C. Clarke's '2001: A Space Odyssey' is another great one. In this novel, the encounter with an alien monolith is a central part of the story. It's a complex exploration of human evolution, technology, and our place in the universe. The alien presence in the form of the monolith drives the plot forward and makes the reader question the nature of intelligence and our relationship with the unknown in space.

One common theme is the encounter between humans and aliens. It can be a friendly first contact like in 'Contact' or a hostile invasion like in 'The War of the Worlds'. Another theme is the exploration of different forms of life. Aliens in these novels often have unique biological features and ways of living. For example, the sandworms in 'Dune'.

Yes, they are quite popular. Many readers are drawn to the unique combination of science - fiction and romance. The idea of falling in love with an alien offers a fresh take on the traditional romance genre. It allows for exploration of different cultures (alien cultures in this case) and how love can transcend species boundaries.
