Soooo, first rule is I'm still anti-Kindle and so can't deal with anything hardback/likely to breach my easyjet weight allowance (sorry The Girl on the Train / The Goldfinch)...
Books I have loved reading on holiday (in no particular order)
Anything by Victoria Hislop
Cazalet Chronicles
Most books by Sarah Waters (except The Little Stranger - WTF?!)
Hunger Games trilogy (ditto Northern Lights)
The Rosie Project
Longbourn
Anything Audrey Niffenegger
The Night Circus
Books I have loathed and have given me the rage:
We are all completely besides ourselves
The 100 year old man who climbed out of a window and bored me into submission...
I'm sure there are more in the latter camp but they're the ones that spring to mind...
PS I'm a book a day girl so pleeeaaassee save me from badly chosen book hell!
