I'm planning on getting the entire Dark Tower series books, maybe purchasing the first 3 and once I finish them, continue.
How much do you recommend them?
I've just started the last book. It's a really weird series and like nothing I've ever read (in a good way). The series was written over the course of about 20 years give or take and it makes it a strange read, at least for me. Each book has it's own kind of feel and they don't all flow together like one large story (in my opinion) but that's not necessarily a bad thing. Book one is quite short, loads of weird shit happens and I was left not really knowing what was really going on. Not everything about the world it's set in is explained, or what's really evening going on at times.
Book 2 is my favourite, it introduces some more characters and it's more structured.
Book 3 is kind of cool again but feels different.
Book 4 is like a whole prequel story.
Book 5 is all different again in a different setting but feels more structured than some of the other books.
Book 6 was really quite strange and there was quite a lot of things that I didn't really understand and wasn't sure why they happened (but I may not have been paying enough attention).
Just started book 7 and it's off to a good start. It's freaking huge and I have literally no clue where the story will go or what will happen.
That probably didn't really help
other than this series I've only read Carrie and The Shining by Stephen King so I can't tell you how it compares to some the majority of his work but I do enjoy it. It doesn't spoon feed you the answers and it really surprises you by going all over the place. It certainly isn't predictable at all and it does have some really good characters.
Hope that rambling mess helped in some way
