But note: Don’t give away your book just on your website. Give it away on high-traffic websites targeted to your topic or audience. Ask the people behind those high-traffic websites and blogs if you can make a special offer to their visitors, something that should attract more repeat visitors to their site or blog.
Final point: Create a better book cover. The above book cover can’t possibly do justice to your dad’s photos and war memories. Get a cover that actually looks like it’s been designed not just thrown together. This is really important since you want to ask a higher price for your print versions.
