Pride and Prejudice .. Jane Austen
Rebecca .. Daphne Du Maurier
Lord of the Rings .. JRR Tolkien
The Harry Potter series .. JK Rowling
Wuthering Heights .. Emily Bronte
It's so difficult to pick only five .. you have to keep it really tight .. if it was a list of all my fave books it would also be peppered with Dickens and Trollope (A), CS Lewis, Terry Pratchett, Susanna Clarke, Stroud and Abercrombie, Charlotte Bronte and Nancy Mitford (infact the Mitfords in general) .. not to mention Stephen Fry.
Just five is difficult.
