Such a tough tough choice as I don't tend to give books as gifts unless it is kids birthday presents, then they choose what they like.I did however join in with World Book Night when it started and the 2 years following (sadly they didn't want me in 2014 :( ).
If you've not heard of World Book Night it is an annual celebration, run by the Reading Agency, which takes place on 23 April. Every year they ask for passionate volunteers to give hundreds of thousands of books away in their communities and share their love of reading with people who, for whatever reason, don’t read for pleasure or own books.
