As I'm pressing on through Anna Karenina (I'm on page 217, and so far I don't like anybody. But I am assured it gets better) and so don't have new review-ish ramblings, I'm instead gonna once again take inspiration from Smart Bitches, Trashy Books: specifically a feature entitled "Help a Bitch Out," in which readers share memories of a plot and commenters try to come up with the title of a book.
There is a horror novel I read in elementary school, possibly middle school (late 80s, early 90s). I remember almost nothing about the plot, but it featured one image I've never forgotten: there was some kind of magical maze(?), at the heart of which lurked a huge, vaguely demonic, white big cat (cougar-type, no mane). It had a name, which I've forgotten, and it killed people. GRAPHICALLY.
I'd thought for a while it was a Peter Straub novel, but looking through his bibliography didn't jog my memory (his website has a nice little display of all the covers). I don't think this is something I'd want to read again--but DRAT, I want to know what it is? Little help?
