This remains one of my favorite novels, if not the most. It's a traditional Gothic novel, complete with romantic ANGST, ghosts, destructive love, moors, societal conflict, and stubborness. add in that a good portion is told via a maid to our narrator, giving it a word of mouth feel, it's an excellent intro to the Gothic style.
It's also a classic on it's own. High school students migth still have this on their reading lists even now in the age of the "Modern Classic." And the girl or boy who never reads this is in a state of literary impoverishment, indeed.
I've read this book nearly 15 times, and might go off and re-read it here soon.
