Someone decided to send my unpublished manuscript off to a vanity press in order to give me a bound copy of my book for my birthday. I'm kind of freaking out about it now--they didn't ask for my permission, of course, since it was a surprise. I believe they only printed the one copy, and the brochure for the press said that all rights remain with the author (which they'd better, since I didn't sign anything!). Is this likely to cause any problems when I seek publication? Should I take any form of action, or can I relax?
