Y: Well... I don't think that he would like such books. Perhaps, you may help me to choose one for him?
A: Of course. Can you tell me about your cousin's genres that he likes?
Y: He likes modern literature, especially science fiction.
A: I see. Well, I think he would like "Do Androids Dream of Electric Sheep?" of Philippe Dick or "The Martian" of Andy Weir.
Y: Oh, I don't even know what is best to choose...
A: I see. I recommend you to buy "The Martian". You see, yesterday I started to read it and, objectively, this book is fascinating. Everyone who likes space fci-fi should read it.
