And here's the shortlist, with the judges' age recommendations:
Sputnik’s Guide to Life on Earth by Frank Cottrell Boyce (8+)
The Bone Sparrow by Zana Fraillon (11+)
The Smell of Other People’s Houses by Bonnie-Sue Hitchcock (13+)
The Stars at Oktober Bend by Glenda Millard (12+)
Beck by Mal Peet with Meg Rosoff (16+)
Railhead by Philip Reeve (12+)
Salt to the Sea by Ruta Sepetys (13+)
Wolf Hollow by Lauren Wolk (10+)
Five and a half titles by women, two and a half by men. Cottrell Boyce, Peet, Reeve and Rosoff are all past winners and Sepetys is a past shortlistee. If
Beck wins, Peet will be only the second posthumous winner.
Beck also has the highest age rating I've seen the judges give a book - there's an advisory note on its content
here. Three novels by British-based writers, three by American-based, two by Australian-based.
As I've done every year since 2009, I'll be reading the whole shortlist, hopefully in time for the winner being announced on 19 June.
