I hereby apologize if there were issues with anything that you downloaded when you got the entire book. I THOUGHT I had appropriately exported the HTML files so they were in good shape. Our wonderful webmaster dashed those hopes for me, and redid the MOBI file. I have no idea how to make links in the PDF file to each chapter - if someone knows, let me know, and I'll do that. I use Calibre and Sigil. I want to give you a perfectly formatted book - even if I am evil with the cliffhangers. I will continue to play with things during the summer, and will upload something with fixes and other stupid errors corrected as soon as I can. (University of Oregon - NOT Oregon State!)
