Sure. 'The Hitchhiker's Guide to the Galaxy' is a great start. It's funny and easy to get into. The concepts are wild but not too difficult to understand. Another good one is 'Ender's Game'. It has a relatable main character in Ender, and the story moves at a good pace. It's a good introduction to science - fiction themes like war in space.
Definitely check out 'The Invisible Library' series. It has elements of mystery and adventure along with science - fiction concepts. It's not too complex and can draw in new readers. Also, the 'I, Robot' series by Isaac Asimov. It has short stories that introduce basic science - fiction ideas about robots and their relationship with humans in an easy - to - digest manner.
