The Dark Tower - The Dark Tower (Book 7)

The ka-tet of Nineteen's reunion was short-lived, as the gunslingers must once again separate to accomplish the two tasks on which the fate of the Dark Tower depends: putting an end to the vile work of the Breakers destroying the Beams, and saving the writer Stephen King from a predetermined death that would inevitably doom them all.

And this is only a prelude to the confrontation with Mordred - a hybrid monster born of Mia/Susannah - the last heir of Eld's lineage but also of the Crimson King, who has not yet played his final card.

For Roland of Gilead, the Tower comes at this price... a price he will have to pay with his entire being, for the survival of all worlds.
