The message was, it's a great start, especially for a first-time author, but it still needs a bit more work before it truly has a chance to stand at the professional level.
I'd rather get the book done right than simply get it done, so I made the painful choice to temporarily remove it from sale and spend the time and effort to make it even better.
If you have purchased the first edition, please feel free to contact me directly. I will be happy to gift you a copy of the revised edition when it becomes available.
