The Dark Tower series follows Roland of Gilead, the last Gunslinger or Knight of the Old World in his quest for the Dark Tower. Throughout, his past and motives are slowly being revealed. The world through which he travels is in some ways reminiscent of our own, and the implications of the similarities just keep growing..... An absolutely superb, ongoing story from the master storyteller. Highly recommended, and please do read the books in the right order - it's worth it!
