Books for sixth formers

I want some books to recommend to my IB students. I'm thinking novel. travel stories, etc. I have loads for Zimbabwe but not so many for the other areas we cover. They're the 16-18 year olds so we can recommend just about anything. Does anyone know any good novels, etc for the following periods - India 1900 to today, Zimbabwe for a similar time period, Poland for a similar time period, USA, Canada, Cuba, Argentina and Brazil from about the 1920s onwards and the cold war. I do have some books (and certainly some of the obvious American ones like grapes of wrath and the great gatsby)

sorry for being dumb but whats IB?

International Baccalaureate. Its an alternative qualification to A level. Its much broader as they have to study their own language, another language, maths, science, a humanities and one other subject although you don't get the depth you do at A Level. Our school offers both

I have no idea on books but an a level alternative sounds really interesting!

I read White Tiger not long ago which if I remember correctly was set in India and was quite interesting x

Thanks Kate. I'll add it to my list. I have just remembered I made a list for Year 9 for India so will have to dig that out and see what books I put on it
