The book that I just downloaded has very small print even on Ultra Large font. This makes it hard for me to read it. Changing the resolution makes the letters short and fat. (not much of an improvement)
I copied a page to a word document and increased the font. That worked ok. After reading a couple of chapters the copy function quit working.
Is there another way to make the letters bigger?
I found the answer. Open the book in my web browser and I can zoom up to 400%.
