Hey Jeremy,
If you're reading this, firstly, thank you! It looks awesome and I have purchased this on UK Amazon to read over the Xmas period. Two points, though:
A) Please generate an HTML version of the Table of Contents and consider putting that on your site, rather than making me guess it's in "First Pages", download a PDF, etc. I think you'd find the return on investment on getting a landing page expert to create a mini-site for the book worth itself many times over...
B) Invest your first sales profits into getting someone to turn this into the epub or mobi your audience are asking for.
