A Torre Negra

The Dark Tower VII

Roland’s ka-tet is reunited, but not without cost. The last episode of the story takes them on the final stretch of their journey to The Dark Tower. Though they have rescued Susannah, there are still enemies who must be dealt with along the way and who could be their ultimate destruction. Constant readers will recognize characters from past books, who like the ka-tet, have found themselves caught in the spider's web spun bythe Crimson King? Gan? Questions are answered and others asked. The journey is long and ka is but a wheel. (source)
