Hi Byrnzie,
I really love your work "In The End". I would like to use it as the cover of a book I am self-publishing. I do not intend to sell the book, or make any money off it at all - I've written it mostly for myself. So the bad news is I can't really promise you a percentage of sales or anything. I would, however, credit you in the acknowledgements with a link to this page. I'm willing to pay a fee to use the image as well, as long as it's reasonable. If you're interested, contact me at facebook.com/sean.freeburn
