It's been three months and COAL is now available on most major retail web sites where e-books are sold. I'm still working on getting it up on Allromanceebooks.com and a few more sites.
But here are a list of places where it is for sale:
Barnes & Noble
And still on Amazon.
I know it's up with my other published books on Smashwords as I publish this post, but it might take a while for it to be added to the other sites. I'll keep checking over the weekend.
