Rainbow Mars
Larry Niven weaves together time travel and fantasy to create an utterly unique novel on the origin of the Martian "canals.". Hanville Svetz was born into a future to match the sorriest predictions of Greenpeace. Most of Earth's original life forms are extinct. It is Svetz's job to go back in time and retrieve them, or at least it was until his Institute for Temporal Research was transferred. Now, with a new boss obsessed with stars and planets, Svetz must figure out why the Martian canals have gone dry and what that means for Earth's future. Because Mars was inhabited. When Svetz learns how the sapient Martian species were wiped out he realizes that Earth could soon fall victim to a similar fate. Together with his dog, Wrona, a visitor from the distant past, and Miya, an astronaut with her own complex history, Svetz must struggle to unravel a puzzle that will tax not just his rational mind but the very limits of his imagination.
Beyond its central premise, the book can be read through the connected lenses of Fiction, Nonfiction, Science Fiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book
This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.
A comfortable full-length choice for steady daily reading.
Begin with its place in Fiction, then notice where the book resists that label.
Read for connection, not completion.
Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.
Three questions to carry with you
- What does the central character want, and what do they misunderstand about that desire?
- Which detail or relationship changes how you interpret the story?
- What feeling or question does the book leave with you after the plot moves on?
