The world of Young Adult (YA) fiction is enjoying a long-running boom. Sales are consistently buoyant, with YA novels reaching large numbers of mature readers as well as their traditional teen market. So it is apt that this on-trend literary form is celebrated as one of the book world's most exciting, malleable genres.

Bookseller magazine's Young Adult fiction award - the coveted YA Book Prize - is in its second year. This time round the shortlist showcases outstanding examples of work by talented writers across this wide-ranging category. There is plenty here to keep YA aficionados happy, with subject matter ranging from gritty social issues to entire fantasy worlds.
