ColonelBrandon - utterly agree with your 30 page rule. It drives me mad that DH will continue to read something he has admitted is crap, he says feels like it would have been wasted time otherwise...but FGS, you're wasting even more precious reading time by finishing it ! Gah.
Anyway, thought I would put my suggestions forward. I read books by the ton from the library and we seem to have similar likes/dislikes, so you never know 
For fantasy have you read any Robin Hobb ? I personally think the Assassins trilogy is excellent, 'The Name of The Wind' by Patrick Rothfuss also worth a look (if you can get over a couple of cringey names, nothing too bad, though)
'Excellent Women' by Barbara Pym - very cosy
For lovely huge chunky books - have you ever read any Dan Simmons? 'The Terror' and 'Drood' are loosely based on historical events ('Drood' concerns Dickens, obviously!) He has also written some SciFi/Fantasy 'Ilium' is pretty fantastic IMO.
I love a bit of Rose Tremain for historical fiction, ever read 'Music and Silence'? (Also Sarah Dunant, I've really enjoyed some of hers)
I've got two books by a guy named Andrew Miller waiting to be read 'Pure' and 'Ingenious Pain' (I think that's the title...) The reviews of his stuff are excellent so I can't wait to read them.(also got 'The Childrens Book' waiting - I too am a sucker for a pretty cover!)
HTH
