Dark Tower IV: Wizard and Glass.
The tale is timeless, the adolescence is beautifully realistic, the story seems to have this ancient prose to it, the characters are perfect, the tragedy is heartbreaking (Those who read the end know the scene which just...snaps your heart in two), the gun battles get your blood pumping, and there are descriptions of the mythological significances of the moon ever so often.
After I put the book down I said out loud "This series is the official sequel to Sir Thomas Chancellor Malory's "Le Morte De Arthur". Officially.
I love the whole series, but this one just stands out as the best one.
Also, anything by Lovecraft.
