Okay, I just spent the last couple of hours finding out how to convert and putting The Riddle of Ryu up at Amazon. Not hard, but definitely nerve-wracking, since I have a long history of technology disasters, many of which I made use of for my upcoming YA book.
Anyway, Ryu should be available for the Kindle in the next day or so. Only $1.99. And find out why he's wearing a bedsheet from Ralph Lauren (can't see it with the cover, but he is)!
