It's definitely not a lightweight beginner's introduction, but
I've found

Better Type, by Betty Binns

to be indispensible.  It's a large-format hardcover, but you can
find it remaindered for cheap if you look around.  The book goes
into great detail about how factors like line spacing, line length,
point size, and design of typeface (evenness of stroke weight,
x-height, etc.) affect readability.  When you've gotten the basics
out of the way and want to learn more about the fine nuances of
type color, this book is an absolute must.
