The novel alternates between non-linear "Two" and linear "One" chapters. Zelazny explained, “I did not decide until I was well into the book that since there was really two time-situations being dealt with (on-Road and off-Road—with off-Road being anywhen in history), I needed only two chapter headings, One and Two, to let the reader know where we are. And since the Twos were non-linear, anyway, I clipped each Two chapter into a discrete packet, stacked them and then shuffled them before reinserting them between the Ones. It shouldn’t have made any difference, though I wouldn’t have had the guts to try doing that without my experience with my other experimental books and the faith it had given me in the feelings I’d developed toward narrative.”
