Hi azteclady, do you mean for GB&U or somewhere else? I have been so bad at promo I may need more clues. I am ready, willing and able to guest post for anyone willing about I might conceivably know about. I will also tell jokes, juggle plates etc as required. :)

TGTBTU is one. Perhaps Karen's
Super Librarian Wendy might be another
bam/Dionne Galace's
There's a bunch others:
Nose in a book;
sula's space;
Kristie(J)'s "Ramblings on Romance";
The Book Binge;
RR@H Novel Thoughts and Book Talk;
Danette's Chatting Lounge;
Jennifer's Random Musings

I'm leaving a few out, I know, but those are some you may want to hit with an offer for an interview, perhaps a giveaway copy (either of the book or another in your backlist) for one commenter; perhaps a few guest posts with tips on epublishing or writing, etc.

Think about other epubbed authors' blogs too--Bettie Sharpe, Shiloh Walker, Ann Bruce, Sarah McCarthy, Shelby Reed, Sela Carsen.

I dunno. Jest spouting off here.
 

I will admire your efforts, and be utterly useless with suggestions...

I'm too damned boring to be good with the interview stuff, so I'm in no position to offer advice on that.
