Well, I dont know if you all remenber, but in the vol 2, in the beginning, Roland goes to West, and there he finds the sea and the doors, etc ... but suddenly he decides to go north, and that's okay. But just in the next chapter, quoting the book:
"The sea to his right, the mountains to his left,the gray, shell-littered sand under the feet of his cut-down boots."
How can the sea be in his right, if the sea is in the west, and he went north? The sea should be in his left.
If there's some mistakes in my text, I'm sorry, english is not my first language.
