Which author will win the battle for the Best Children's Book of the past decade?

The viewers of the BBC series Blue Peter and programme [British spelling] editor Tim Levell will be deciding which children's book of the past decade is the best.

Luckily, this will not be another People's Choice award fiasco, where four of the five choices were Harry Potter stars, and the fans spread the votes out among the four with the end result of losing to the only other nominee. In this case, the vote is strictly for Harry Potter and the Order of the Phoenix.

The boy wizard takes on David Williams's Mr. Stink, and Anthony Horowitz's Alex Rider Skeleton Key, Jacqueline Wilson's Candy Floss, Francesca Simon's Horrid Henry and the Football Fiend, Lemony Snicket's A Series of Unfortunate Events: The Austere Academy, Jeff Kinney's Diary of a Wimpy Kid, Michael Morpurgo's Private Peaceful, Charlie Higson's Silver Fin, and John Grisham's Theodore Boone.
