All backers of the Dracula Kickstarter will also get one copy of Dante's Inferno for free. This is because the Kickstarter has gone way beyond its initial target and is my way of saying thank you, for backing the project while its on Kickstarter.
Chose your pledge reward and if you want additional copies, simply add £6 per additional book.
