In Other Worlds is a 1985 novel by American writer A. A. Attanasio, the second in his Radix Tetrad. It contains humans, zōtl, Rimstalkers, other spatial dimensions, and time-travel/temporal distortion as do other novels in the Radix series, though they are re-envisioned.
Carl Schirmer's life is transformed when he is turned into energy by an eighth-dimensional being and transported to a faraway world at the edge of a black hole.
What follows is a thrilling ride similar to Flash Gordon involving a woman from the end of time, a man who can live off sunlight, and an alternate, paradisaical Earth in which World War II never happened.
