Just read a P.D. James- A Certain Justice- not bad, and The Russia House by John le Carré, if you like that kind of thing.
Otherwise, Wild Heart: Natalie Clifford Barney and the Decadence of Literary Paris by Suzanne Rodriguez is brilliant. Even if you're not particularly interested in the topic. Likewise with Donald Sturrock's biography of Roald Dahl.
Anything by Chaim Potok
The Secret History by Donna Tartt, have you read that? seems like everyone has!
There's always Alexander McCall Smith. Aww he's so fab. No1 Ladies' Detective Agency.
Frederick Taylor's book 'The Berlin Wall' is a history book, yes, but not dry at all. Completely readable and the pace is very fast, there are lots of little anecdotes and it's absolutely unputdownable.
Remains of the Day? Bit sobering for a holiday maybe.
Jalna series maybe, although that family are so horrible to each other most of the time! by Mazo de la Roche, I think.
Ever thought of getting into a kids series? I love them. Trebizon, Drina, Jennings especially. If you come across a stack in a charity shop- buy them and get stuck in. It's great to have a series on holiday.
I keep recommending The Children's Book (A.S. Byatt) to everyone. For a reason! It's so so well done, so well executed and just the kind of controlled ramble everyone likes, specially in an historical novel like this. And the cover is gorgeous too 
Mame by Patrick Dennis is funny and goes by like a flash. Quirky woman with bemused orphaned nephew.
Zami is good too.
You can tell I'm not having a particularly dynamic Saturday! think I'll stop and slope off now...
