The final volume shows the gunslinger Roland on a rollercoaster ride filled with exciting triumph and painful loss in his tireless quest for the Dark Tower. Roland's group of pilgrims remains united, even though they are scattered. Susannah-Mia has been taken to New York to give birth. Fearing what might happen, Jake, Father Callahan, and Oy follow. Roland and Eddie are in Maine, searching for the place that will lead them to Susannah. As he finally approaches the Tower, each step is shadowed by a terrible and eerie creature. And ultimately, he realizes that he may have to walk the last dark path alone. You've come so far, go a little further, go all the way. The sound you hear could be the door slamming shut behind you. Welcome to the Dark Tower.
