... I've only read the first book of the Dark Wossname series, which did not inspire me to read any more once they were actually written.
I was feeling similarly uninspired by
The Gunslinger but will add my voice to the doubtless many who will have told you that it is worth persevering.
The Drawing of the Three is much better (
Wizard and Glass is utterly brilliant), and many of the things that seemed weird and disjointed in
The Gunslinger will only make sense in the context of the later books.
And I don't think King uses 'quarter of' very much in any of them.
(Edit to add: because I'm a sad bastard, I checked this and found 4
'quarter of's, all in
The Waste Lands. Interestingly, King uses
'quarter to' twice in
Wolves of the Calla and twice in
The Dark Tower.)
