I just wound up making the main text Charis, the Trek ebook font of choice until about a year ago when they started putting a whole bunch of fonts in each book to try and closer match the print versions.
Actually, once I assigned the main text to Charis and saw it on my Nook Tablet, it looks pretty darned close. The main difference is the quotes look different than in the print version but I didn't care for those anyway. The text is close enough to make me happy and, perfectionist though I am, it wasn't worth spending that
much time on. I wanted to actually read the book!
Oh well, time to go finish the yard so I can start chapter two!
Thanks for the suggestion.
