Snuff Fiction, Robert Rankin
Count Karlstein, Phillip Pullman (I will read this one first)
The Wind in the Willows, Kenneth Grahame
Pride and Prejudice, Jane Austen (not likely to be as good as Persuasion but there you have it)
The Adventures of Sherlock Holmes, Arthur Conan Doyle (expect this won't really be to my tastes and will be left behind)
Night Train, Martin Amis
I feel confident I can read at least three of these on my trip, one each way on the plane, and one in the evenings or on the beach. Mmmm, books. How I love them.
