According to Larry Niven, time travel is logically impossible - sheer fantasy. So when time-agent Svetz heads back from polluted future Earth in search of extinct animals, he tends to sideslip into fantastic, fictional worlds.

Rainbow Mars combines both space and time travel to explore Mars in the deep past, before it was a dead world. Svetz and companions are soon in big trouble.

Fun for experienced sci-fi readers who can follow the in-jokes and the switchback ride through tangled alternative histories. The earlier, funnier Svetz stories are included as a bonus.
