I have removed my ebooks from Google Play and all stores but one. Amazon. The decision wasn’t easy, but as an author I believe it is the right one. The retailer just launched Kindle Unlimited, which some social sharers call the “Netflix for books”. Subscribers pay $9.99 per month for whatever written or audio books participate in the program, and Amazon claims 600,000 titles.
To join the Kindle Unlimited program, independent publishers must put their books into KDP Select and give exclusivity for 90-day intervals (or longer). As a writer and reader, I love the “Netflix for books” concept, but as an independent publisher my participation means commitment to Amazon.
