14YO niece: used to read a lot. Has little time now due to academics and dance classes. With these constraints, anything is fine. I'm thinking of something which is light reading for teens, probably funny and relaxing 1 or 2 books.
13YO nephew: computer geek(just knows a lot of specs, doesn't code or anything), introverted but not nerdy. Does not read often. Very calculative(selfish) in terms of tangible benefits. I have already purchased Billionaire Boy by David Williams. Need a 2nd recommendation. Probably a scifi novel, manga or comic, or light non fiction.
9YO nephew: Reads often and has his library. Currently interested in all things mechanical, automobiles, airplanes etc but obviously can't understand the math behind them. I need 2 recommendations, one a scifi for kids and 2nd a book with examples of great inventions or mesmerizing stories about great inventions. Space missions or facts would also be cool but the language has to be kid friendly. A memoir of scientific stories of perhaps Nobel laureates would be fantastic.
I'm based in India so probably need recommendations if the book is sold in subcontinent. Do ask clarifying questions if something is missing.
