This is actually a quote from
Steven King's novel "
The Gunslinger," the first book in the
Dark Tower series.
Jake says this to
our hero, Roland,
the world's last gunslinger in a world that has moved on. Jake is from our
world, from
New York City, and has just died under the wheels of a
Cadillac when
the gunslinger finds him at a deserted
way station.
Roland has pursued
the man in black across the desert, finding
Jake along the way.
Beyond the desert, under the mountains on a decaying
rail track, Jake is clinging to
Roland's arm over a deep
chasm. Yards away,
the man in black tells Roland he must
choose the boy's life, or catching
Walter (the man in black) and being able to continue his quest for the
Dark Tower.
Jake's last words before Roland
drops him are: "Go then. There are
other worlds than these."
