Some person or group called
WonderClub is, without permission, offering in digital and audio (!) formats the five books my briefly active light-verse publishing company printed, and charging handsomely for them. (Most of the authors are Spherians.)
If you've published, you might check out the link to see whether your books are among the extensive offerings. [Edit in: I've been advised that the site's main purpose may be the spread of computer viruses, so anyone wanting to see whether their books are listed should be cautious.]
Before I send a cease and desist message: does anyone have a better suggestion about approaching the matter? Ideally, I'd like to get the authors some sort of compensation for the theft and (attempted) sale of their work. Thanks for any advice.
