To celebrate the end of the Summer Reading Challenge, as well as the beginning of Chatterbooks Week, the Reading Agency is holding a "which books makes you happiest" poll.

Voters choose from 10 books, including Diary of a Wimpy Kid by Jeff Kinney, The Twits by Roald Dahl, and Gangsta Granny by David Walliams. These finalists were selected from 259,000 kid-written reviews and comments, then filtered for the books rated highest in "fun and enjoyment." The polls close on 3 October and results are released on the 13th, so join in and vote soon!

Chatterbooks Week (11-18 of October 2014) is the Reading Agency's way to keep celebrating books through the autumn. Across the UK, schools, libraries and individuals set up reading groups in which children ages four to 12 can read, share and talk about books.

"I know that Chatterbooks groups old and new will have a fantastic time getting together, finding out about great books and chatting." Says this year's Chatterbooks Ambassador, author Jacqueline Wilson.

You, your school, and anyone you know can get involved through the Reading Agency Website.
