The crucial sixth part of King's bestselling epic offers the key to the quest that defines Roland's life. In the next segment of their journey to the tower, Roland and his companions face adversities from all sides: Susannah Dean has been taken over by a demon mother and is using the power of Black Thirteen to escape Mid-World New York City. But who is the father of her child? And what role will the Crimson King play? Roland sends Jake to break Susannah's date with destiny while he himself uses the persistence of magic to reach Maine in the summer of 1977. It is a terrifying world: on one hand, it is real and bullets are flying. On the other hand, it is inhabited by the author of a novel called Salem's Lot. Song of Susannah is driven by revelation and tension. It seamlessly continues the Dark Tower series from Wolves of the Calla, and the dramatic climax will leave readers desperately wanting to read the conclusion of the quest.
