Brainster lists his 10 favorite books and asks others to join him. I'll happily comply with the following provisos: 1) I will not number them--at different times I feel differently about different books; 2) The list is subject to change; and 3) There's some overlap:
Decline and Fall by Evelyn Waugh. Actually love most of Waugh--except, gasp, Brideshead.
Anglo-Saxon Attitudes by Angus Wilson. Brilliant portrait of Ingeborg Middleton, the hero's ex-wife.
A Legacy by Sybille Bedford.
The World of Jeeves by P.G. Wodehouse. Actually anything by Wodehouse but the complete Bertie Wooster/Jeeves stories were the first things by him that I read so I'll pick them.
David Copperfield. For years Great Expectations was my favorite book by Dickens, but now it's this one.
Crime and Punishment.
Anna Karenina. I haven't read War and Peace yet.
The Chronicles of Narnia by CS Lewis. All of them.
Reuben Reuben by Peter De Vries.
Wind in the Willows by Kenneth Grahame.
Update: I forgot Patrick O'Brian's Aubrey/Maturin series. Since I think all 20 volumes are really just one book, I'll add the series to my list.
