If you are interested in Jackie Kennedy Onassis then the book I have on her is very good - I'm not usually a biography sort of person, but its very interesting. I swapped it with someone off here so its now looking for a new home.
The Guardsmen, another swapsie from on here is all about Harold MacmIllan, Bobbety Cranborne, Oliver Lytellton and Crookshanks from their time at Eton through to their deaths - If you are interested in 20th century British politics then its worth a look.
Cheers all, hope your having a reading good time!!
