As part of my outreach strategy, Bibliomania, my story about a near future where paper books are illegal and DRM is mandatory, is going permanently free everywhere. It is already free at Kobo and Smashwords, and it will be free at Amazon after Barnes and Noble posts the new edition to their site and I can get Amazon to price-match.
Check it out, if you haven’t already, and please tell your friends!
Update: It is now available free at Barnes and Noble.
Update 2016-02-18: Bibliomania is no longer permafree, but it can be gotten for joining to my mailing list.
