Right Ho Jeeves by P.G. Wodehouse
The Robber Bride by Margaret Atwood
The Outline of History by H. G. Wells
I would not want to take anything that I hadn't read before. Otherwise, I am likely to pick a book that I find unreadable after a couple of dozen pages and I'd be in serious trouble.
Right Ho Jeeves was an obvious choice since it is my favourite book and always makes me laugh. I don't know if I would still be laughing if I had to read it every day. I hope so.
I would choose the Robber Bride because Charis is my favourite fictional character and I would want to have her on the island with me.
The third book was a really tough choice. I thought of choosing something for its length such as Islandia by Austin Tappan Wright or an Art History book. In the end I choose the Outline of History because of the depth of it. The history of the world from prehistoric times to the end of the first world war covers a lot of subjects and cultures.
