Hhhmmmm - good question, it depends what kind of vacation I'm going on. A beach side vacation - chicklit. Definitely chicklit! Or historical fiction. Give me Lesley Pearse, or Jennifer Donnelly, or Jill Mansell or Nicky Pellegrino. A slightly more intrepid vacation, then I'll pick a few books that are set in the location I'm visiting. But I also like to take along a really big read that I can delve into without any distractions. That's how I made it through, Shantaram, Lord of the Rings and Paullina Simmons', A Song in the Daylight (although that was a struggle!). But, if I was going on vacation tomorrow, I think I'd pack a few Sebastian Faulks novels. I haven't read any of his books yet and I think a vacation is exactly what I need to get started!
