Twitter competition terms and conditions
The Royal Society is asking science book fans 'What's your favourite science book that you've read this year - and why?'
Tania Hershman, author of short story collections, will judge the Twitter competition.
The best five answers will win a copy of the Royal Society Winton Prize for Science Books 2012 shortlist and two tickets to the award event and the after-party, held at the Royal Society.
How to enter
The competition will be run from our Twitter account from Monday 19 to Thursday 22 November.
To take part, simply send a tweet with your answer to the following question: 'What's your favourite science book that you've read this year - and why?'
Please include the hashtag #SciBooks in your answer so that we can find it.
The entries will be judged by Tania Hershman, a member of the prize's judging panel. She'll pick the winners based on originality and creative use of Twitter's 140 character limit.
