ABSTRACT
In most works of fantasy, time travel just happens. Characters step back in time, walk through portals, light candles, or dream themselves elsewhere. In most time travel stories for children (Alan Garner's Red Shift is a notable exception), either moments in time travel at the same pace in all time spaces or protagonists are returned to their own time as if nothing ever happened. Time travel in fantasy is frequently very convenient. Elsewhere in this book I have insisted on Diana Wynne Jones's position as a fantasy writer, but her approach to time travel has been distinctively that of the writer of science fiction. Her time travel narratives exist in the world of the rational, not of wish fulfillment: they deploy recognized theories of time travel.
