Song of Susannah (The Dark Tower VI), by Stephen King
Paperback in Very Good Condition
The next-to-last novel in Stephen King's seven-volume magnum opus, Song of Susannah is a fascinating key to the unfolding mystery of the Dark Tower.
To give birth to her "chap", demon-mother Mia has usurped the body of Susannah Dean and used the power of Black Thirteen to transport to New York City in the summer of 1999. The city is strange to Susannah...and terrifying to the "daughter of none" who shares her body and mind.
Saving the Tower depends not only on rescuing Susannah but also on securing the vacant lot Calvin Tower owns before he loses it to the Sombra Corporation. Enlisting the aid of Manni senders, the remaining ka-tet climbs to the Doorway Cave...and discovers that magic has its own mind. It falls to the boy, the billy bumbler, and the fallen priest to find Susannah-Mia, who in a struggle to cope, with each other and with an alien environment, "go todash" to Castle Discordia on the border of End-World. In that forsaken place, Mia reveals her origins, her purpose, and her fierce desire to mother whatever creature the two of them have carried to term.
Eddie and Roland, meanwhile, tumble into western Maine in the summer of 1977, a world that should be idyllic but isn't. For one thing, it is real, and the bullets are flying. For another, it is inhabited by the author of a novel called Salem's Lot, a writer who turns out to be as shocked by them as they are by him.
