if you had asked me this question before this past rereading it would have gone like this:

wizard and glass
the waste land
the dark tower
the drawing of the three
the gunslinger
song of susannah
wolves of the calla


but now i'm all completely fucked up. and it's all this rereadings fault! i haven't cried so much since the final books first came out. and i couldn't stand susan in this rereading. i don't want to say
Spoiler:
i couldn't wait for her to die but, well. . . . let's just say i cried when she called out roland i love thee but i was more upset by how roland took it than by her actual death.
and just sitting here thinking about the dark tower (the final book, hear me i beg) i am starting to cry. maybe it's the weather. yes, that is surely it. just the weather.

my order now is:

the dark tower
the waste land
the drawing of the three
wolves of the calla
song of susannah
the gunslinger
wizard and glass
