I'm not being paid to write this or given anything in exchange, I just thought you'd be interested to know that Top That! Publishing (who do send me books to review every so often) are very kindly making all their apps and e-books free to download until midnight tonight to help celebrate World Book Night.
I've downloaded most of the apps as The Boy loves the Mixed-Up Monsters/Animals that we were playing with the other day, and I've downloaded all of the picture books into the iBooks app on my new iPad (did I mention I had one of those?).
There's not just pre-schoolers picture books available, there's a whole load of fiction and non-fiction books for children up to about ten years of age, especially engaging for reluctant boys!
