First and best, David Copperfield. I know, I know: there's so much wrong with it. But it's Dickens' Pride and Prejudice, his 'darling child'. It's not as good as Great Expectations, any more than P & P is as good as Mansfield Park but next to Middlemarch it's my favourite book for getting lost in. I also read
Nancy Mitford's four novels which begin with The Pursuit of Love.
Gaudy Night and Busman's Honeymoon which should surely always be read as a pair.
Henrietta's War and Henrietta Sees it Through by Joyce Dennys. If you don't know these and you like the diary format, seek them out. IMO they are better than The Provincial Lady.
New books I read were Friends, Lovers, Chocolate by Alexander McCall Smith.
A Short History of Tractors in Ukraianian by Marina Lewycka. I heard this read on R4 and enjoyed it all over again.
