Song of Susannah

Song of Susannah is the second-to-last book in Stephen King's Dark Tower series.

Spoiler warning: Plot or ending details follow.

Taking place mainly in our world (New York City and East Stoneham, Maine), the ka-tet are split up in different places and different 'whens' to find out more information pertaining to their quest of the mysterious Dark Tower. Susannah's trapped in her own mind, while Mia, the former demon and now a very pregnant white woman, has taken over her body in the summer of 1999 in New York. Jake, Oy, and Callahan follow her to try to stop the birth of Mia's baby and save Susannah. Roland and Eddie travel to Maine in 1977 to buy a certain vacant lot in New York, and run into a young author named Stephen King. "Song of Susannah" is more action and explanation than the previous books in the series, leading up to the final cliff-hanger before the series' epic conclusion.
