Oh Lord, where do I begin?
I mean, there are individual books that I re-read often, even though I don't much care for the rest of that author's work (The Stand
by Stephen King is a good example; I think it's great, but I'm a bit meh about the rest of his books, ditto The Moon is a Harsh Mistress
by Robert Heinlein, but I can take or leave the rest of his stuff). In this category I'd also put A Town Like Alice
by Nevile Shute and those one book wonders like The Raw Shark Texts
by Steven Hall and Shantaram
by David Gregory.
I like crime novels and thrillers, so I like Michael Connolly, Lawrence Block, Robert Crais, Stieg Larsson, Lee Child, Sue Grafton, Val McDermid, John Lescroart, Dennis Lehane, Jeffrey Deaver, Ian Rankin - but (if they'll forgive me for saying so) they're mostly fodder rather than literature. I mean, I'll re-read these, too, but I wouldn't take them with me on a desert island.
I like historical novels, so I'll always have a soft spot for Georgette Heyer and Ellis Peters, as well as more recent contenders such as C J Sansom.
Then there are the classics - Jane Austen, Charlotte Bronte, Dickens, Tolkien.
Phew! It's an endless list. But I guess if I ever had the skill to write (which I don't), I'd want to write like Margaret Attwood, David Mitchell, Barbara Kingsolver, Amy Tan, Sophie Hannah, Julian Rathbone or Maria McCann. These are the writers who I most admire.
Oh, and I know this list is incomplete - no humour, no Neil Gaiman, no non-fiction. Yikes!
Edit: Three hours later and I realise, belatedly, that I've omitted Kate Atkinson and Sarah Waters from my 'writers I most admire' list.
