Here are the results of our most recent newsletter competition:

Last week, we had three copies of The Lost Book of Adventure, recently published by Lincoln Children’s Books, to give away.

We asked: Through which South American country does the Jari River flow?

And the answer is: Brazil. The winners are Mike Clayton, Catherine Booth and Catherine Vulliamy. Your prizes should be with you very soon!

Thanks, as usual, for all the competition entries. To be in with a chance of winning our next prize – one of three copies of Barry Lopez’s Horizon, published today by Bodley Head  – make sure you’re signed up to our mailing list before 11am tomorrow. The sign-up bar can be found in the top right-hand corner of this page.
