Castaway companions

For some, Sunday just would not be the same without tales of country folk and eight esoteric pieces of music. I wondered what it would be like to choose books rather than tunes, what criteria one would use. Upon reflection, this one has decided on books I remember reading, their effect on me and why I remember them. The order is chronological (for no particular reason) and there seems to be more from recent years. Perhaps time filters choice...
1. Green Darkness by Anya Seton. A historical novel which introduced me to the idea of reincarnation.
2. The Hobbit by J.R.R. Tolkien. A grown-up read whilst I was in a children's ward recovering from an operation.
3. Sophie's World by Jostein Gaarder. Recommended to make me think. I loved the way the story puled the reader in one direction then pushed you off balance by going somewhere else entirely.
4. Jumping the Queue by Mary Wesley. Written by an older woman, discussing suicide in a gentile way. A revelation.
5. Landscape of Lies by Peter Watson. A treasure hunt based around a painting (a copy of which is included in the frontispiece). Fun
6. Time Traveller's Wife by Audrey Niffenegger. The hero takes a backseat as her friend/husband gets all the action and she copes and waits...
7. The Elegance of the Hedgehog by Muriel Barbery. Grabs your attention by being gentle and unpredictable.
8. Selected works by T.S. Spivet by Reif Larsen. What a joy, with its intricate sketches in the margins! I really must replace my copy, which I gave to a friend.
9. The Night Circus by Erin Morgenstern. I meant to keep the list to eight, but this was so good. I was bereft when I reached the last page and found myself turning back to the beginning to re-read Anticipation.
Instead of Shakespeare, could I have the complete works of Terry Pratchett? And a cooking bible (please don't ask me to choose one - just one?!)
My luxury would have to be a waterproof, solar powered e-reader, on to which the books would be down-loaded. It would of course need a safe pouch for my glasses and a strap from which to hang around my neck as I swim from my sinking ship to the desert island......
