Thanks for the recommendations everyone! I'm going to add the Hemingway titles to my wishlist. They all do ring a bell from the course, and we probably did read some excerpts from them. It also seems that there's a new restored edition of A Moveable Feast
being published in June. Don't know whether it's really worth waiting for that one or whether it's just a marketing scheme.
We also read some excerpts from Mark Twain's books, but I wasn't a big fan of those. Still, I'm going to give one his books a chance in the near future, I might think differently now.
I actually have collection of Lovecraft's stories on my shelves. As it is over 800 pages, I'm saving it for when I have a long holiday. Looking forward to them, I've heard so much good about them. There's a similar collection of Robert E. Howard's Conan the Barbarian that I have my eye on, just haven't gotten round to buying it yet. And I have noticed that I also have a copy of Jungle Book by Kipling already, from my students' days when I bought an entire set of those cheap Penguin classics pockets. Never heard of Andre Norton before, will look into his work as well!
Thanks for all the advice everyone! You've just raised my to read pile to reach the ceiling!
