I don't read a huge amount. I've come to realise I will only keep picking up a book if it's lighthearted and puts a smile on my face (unless maybe I'm child-free for a while and had the energy to get into something a bit more serious)!
Books I've really laughed at include the Hitchhiker's Guide series by Douglas Adams, some comedians' autobiographies, and I've just finished a friend's recommendation, Far Far Beyond Berlin by Craig Meighan, which had me laughing nearly all the way through.
I have some Amazon vouchers and some Waterstones vouchers. Can anyone suggest some others?
