One Million Years AD - Fembot Sally, #5

A disastrous experiment sends Sally Shagwell spiralling through time, though whether into the past or the future is not immediately clear. A dinosaur attack places her firmly in the Jurassic period, but there are primitive people running around here too, in rather revealing loincloths, and if Sally knows one thing it is that humans and dinosaurs never co-existed. Perhaps she has slipped sideways in time, into an alternative reality. Or perhaps she is on a different planet altogether. Only one thing is certain: the dinosaurs are the least of her problems!
