Frozen in Time by Ali Sparkes has been named the overall winner of the Blue Peter Book Awards.
The novel won the award's 'book I couldn't put down' category and went on to scoop the Blue Peter book of the year honour.
Sparkes saw off competition from Guy Bass' Dinkin Dings and the Frightening Things, which was named the 'most fun story with pictures', and Why Eating Bogeys is Good for You by Mitchell Symons, voted the 'best book with facts'.
Tim Levell, editor of Blue Peter, said: 'What is so wonderful about the Blue Peter Book Awards is that the winners are decided by children, which I know means so much to authors. The standard of the books this year has been remarkable.'
Shortlisted titles in the awards included The Boy Who Fell Down Exit 43 by Harriet Goodwin, Frank Cottrell Boyce's Cosmic, Mick Manning and Brita Granstrom's Tail-End Charlie and Peter the Penguin Pioneer by Daren King.
Last year, the Blue Peter book of the year title was awarded to Shadow Forest by Matt Haig.
