Ballet and other book-related obsessions

I just finished with a new volume of a series I love that is set in the world of professional ballet.  I am an armchair ballet fan and have been probably since I was working at the public library as a teenager and found all those biographies about Maria Tallchief (you should go find some yourself because she is completely fascinating, and be sure to watch her on DVD in The Art of Maria Tallchief).

I am not a big fan of modern dance, and the last two volumes of this story have been focused almost exclusively on this kind of dance.  I love the story anyway because I care about the characters, and I can identify with their struggles (especially the main character's inability to fully grasp modern dance).  She seems to be closer to connecting to it, and I am probably better able to appreciate it, but I'm still unlikely to enjoy it.  Not the book's fault.  :)

One of the results of reading this series, published sporadically, is that whenever a new volume comes out, I find myself needing to read Dance Magazine (Yuan Yuan Tan rocks!) and move some ballet DVDs higher up my Netflix queue and maybe see if the library has any more photo books.  One of these days, I'll have to see The Red Shoes and The Turning Point.  I should also see Dancing for Mr B, again.  I kind of want to watch Fame, too . . . 

Are there any books that do this for you?  (Make you passionately want to learn more about a subject or just immerse yourself in a non-fiction world that isn't yours?)  What are the books or what are the topics?
