OK, I just pulled the trigger on the approval process. It takes up to 72 hours for Amazon to process it.
Pricing... I tried to keep it in the same ballpark as the Ross Bentley series, as size-wise it is very similar. Unfortunately, because I wanted colour illustrations instead of B&W / greyscale, printing costs were higher than the RB cover price.
So the cheapest I could go was $29.99. At that rate I make less per book than the Kindle version. *shrug*. To make the same as the Kindle, it would have to be ~$36 and I don't think people will pay that.
So I guess we'll see.
I caught a couple of additional typos while editing the print version. Those changes will be rolled out into the Kindle version and it will auto-update once I get them done.
