I love reading to my children; especially adventure stories.
And of all the books I've read to them, my favourite (and our eldest's favourite) has been the Binding of the Blade series by L B Graham. Magnificent; brilliant; a work of genius. It's a story of how a world fell and was renewed; very familiar, and yet very imaginative.
I've just noticed that book 1 is available as an e-book for free. What are you waiting for?
