It could also be a problem with amazon.com... None of the other books I ordered last weekend have shipped either, after they claimed they could ship within 24 hours.... It's not the first time I've had trouble with amazon.com taking their time with stuff.
The MSReader version of Volume is listed as the number one Mystery and Thriller eBook on Amazon today
Congratulations! I've read the reviews for it on amazon.com, and most (if not all) are 5 stars. Keep up the great work.
I will still work through LightningSource (the distributor) to try and bring some pressure to bear on Monday ... or at least someindication to them there are issues.
Best regards.
