Having read almost everything that has flowed from the pen of Stephen King, i will no doubt get around to reading his latest work.
Dave50; he can be a tad verbose, but it ought not to detract from some wonderful stories.
Not yet but I have read everything else he has written. Dave yes you could say long winded but I find detailed description is character and works building which I enjoy a lot. I read a lot of fantasy too which is often the same.
