Time Travellers Wife is gorgeous so I second that nomination.
Behind the Scenes at the Museam by Kate Atkinson - one of my favourite books
The Live Ship traders / Royal Assasin / Tawny man trilogies by Robin Hobb - that woman can write!
Can't go past Wuthering Heights - Emily (?) Bronte and for something of a groundbreaker in its day - try The Tenant of Wildfell Hall - Anne Bronte - not as well known as the other Bronte books but excellent.
I love Tess of the D'urbevilles by Thomas Harding - very dark
and if you're interested in something a bit way-out-there - love it or hate it - try The Wasp Factory by Ian Banks - I love it and just thought that for a debut novel it was really brave and original. Other friends have hated it with a passion.

Have fun and let us know what you're reading. I miss discussing books.
