Adam Croft: Meet the independent author who at one point was outselling JK Rowling | Books | Entertainment | Express.co.uk

And the reason he is underneath the radar? It's because rather than having his books printed by a traditional publisher, Adam sells his books via the internet via his own website and Amazon, so readers download them to read on computers, e-readers and mobile phones.

It meant that at one point, he was earning an incredible £2,000 a day in royalties from his books, making him one of the world's most successful independently published authors.

Adam's is an inspiring story for anyone who wants to be a writer but fears that the world of traditional publishing isn't for them.
