About the prize
Each year the Royal Society celebrates the best books that communicate science to young people through our Young People's Book Prize. This year's winner will be announced in November 2015.
The Prize aims to inspire young people to read about science and promotes the writing of excellent, accessible books for under-14s.
A panel of expert adult judges chooses a shortlist of six books, announced each May, before the winner is chosen by groups of young people in Judging Panels across the UK.
