Hi LauraFig. Welcome to SitePoint.
As a print designer for many years, I already have a process and vocabulary. It would be nice to have a book that could take the things that print designers are familiar with and translate them to web design terms.
There's a danger here, because print and web design are very different animals—more different than traditional print designers tend to assume. Trying to bring print design skills to the web is generally a disaster in my experience, because "print thinking" translates very poorly into web design. The web is much harder to control, is fluid and elastic, and print designers find it difficult to break out of the mold of thinking that everything is fixed to a certain height and width and pixel perfect.
So from that point of view, it might be better to approach web design from a completely new perspective, and find out what its needs really are, independent of anything you are familiar with. Then, and only then, bring back in any of the principles from print design that may still be useful, such as typography, white space and so on (you can tell I'm not a graphic designer ).
