A lot of the good books about teaching reading are by and for K-8 ELA teachers. I like Nancie Atwell's The Reading Zone, and I just read a good one by Patrick Allen about reading conferences, which said everything I have been groping toward over the past month or two. I haven't read many books aimed at high school English teachers, but of the ones I have looked at, this one is the best:
The author, Mary Leonhardt, who taught for 37 years and ended her career at Concord-Carlisle, published a bunch of well-received books about reading aimed at parents, but this one is for teachers. Leonhardt writes in a clear, common-sense style, and she is very wise. Basically, she advocates a lot of self-selected reading and daily in-class reading. No wonder I like it!
