Since Amazon is now offering hardcover books for self-publishing, I've gotten some of my more recent book in hardcover.
It's not hard to do, just proceed like you were publishing a paperback book. You might need a separate ISBM number, but don't quote me on that.
My more recent book in my Chronicles of Arcon series is now in hardcover: Alien Enslaved: Chronicles of Arcon - Kindle edition by Seagraves, Janice . Romance Kindle eBooks @ Amazon.com.
Blurb: After his planet's destruction, the Arcon slave, Chase Starstrider, seeks death in every gladiator match. He's tempted by his master’s gift of the curvaceous Earthling whose touch awakens him like no other, but the Intergalactic Gladiator Starship is no safe place for a mate.Kasandra Lee Sinclair, and known as Kaz to her friends, wouldn’t mind rocking the hunky Arcon’s world for a way home to Earth, but there are dangers onboard the spaceship and, in the arena, even for a sex slave like her.
