Ali Sparkes is also author of the Shapeshifter and Monster Maker books
A tale of two cryogenically frozen children from the 1950s, brought back to life in 2009, has won the Blue Peter book of the year award.
Frozen in Time was written by Ali Sparkes, who previously worked on BBC Radio 4's Home Truths.
Her previous books include the Monster Makers and Shapeshifter series.
Dinkin Dings and the Frightening Things, by Guy Bass, and Why Eating Bogeys is Good For You, by Mitchell Symons, also won awards.
Frozen in Time won the top accolade on the special episode of Blue Peter broadcast on Wednesday, in honour of World Book Day.
Best Book With Facts: Usborne Lift-the-flap Picture Atlas - (Alex Frith and Kate Leake); Tail-End Charlie (Mick Manning and Brita Granstrom); Why Eating Bogeys is Good for You (Mitchell Symons)
Book I Couldn't Put Down: Cosmic (Frank Cottrell Boyce); The Boy Who Fell Down Exit 43 (Harriet Goodwin); Frozen in Time (Ali Sparkes)
Most Fun Story with Pictures: Peter the Penguin Pioneer (Daren King); Spells (Emily Gravett); Dinkin Dings and the Frightening Things (Guy Bass and Pete Williamson)
Ms Sparkes said: "I really think the Blue Peter children's book award is the children's author's Oscar and I know a lot of my author friends agree.
"All they've been able to say since they heard I was shortlisted is 'Will you get a Blue Peter badge? Will you get a badge?!'
"And what makes it extra chunkily lovely is that Frozen In Time is such a British book and shares so much of its British spirit with Blue Peter.
"I think anyone who reads it, of whatever age, will make that connection. I really wanted it to be about adventure, friendship, tolerance, decency, modern life, history, cookery, handling fear - and a lot of laughs."
The Blue Peter Book Awards have been recognising and celebrating the best children's books since 2000.
There are three categories of awards: most fun story with pictures, best book with facts and book I couldn't put down. The favourite of the three is voted Blue Peter book of the year.
Dinkin Dings and the Frightening Things won the most fun story with pictures category, while Why Eating Bogeys is Good For You took the title for best book with facts.
Frozen In Time was named book of the year after winning the book I couldn't put down category.
The nine shortlisted books were voted for by children.
Tim Levell, Blue Peter editor 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.
"I am of course delighted for Ali and I hope she enjoys the rest of 2010 knowing that she has written the Blue Peter Book of the Year!"
