I have been doing a lot of cross-promotion through the website StoryOrigin and now, BookFunnel. Authors pool their connections and readers to reach a larger audience.

Authors offer free sample books, review opportunities, sales announcements, and Kindle Unlimited titles.

Here are the campaigns I am part of and the authors that are sharing each others works. Some free book offers require a newsletter sign-up, which is a small non-monetary price to pay to try out a new indie author.
