Whether you're in the mood for robots, westerns, or complex ruminations on the nature of mortality, these reads will make for ideal, thought-provoking, entertaining complements.

Who better to start with than the director of the origin Westworld? Much of Crichton's sci-fi oevre is a natural fit here, but Sphere is a particularly compelling choice, crafting a powerful sci-fi-thriller rooted in the boundless potential of the human imagination. Buy it here.

This fascinating futuristic novel, about a man traversing a 50th-century landscape to try to get himself home, is inspired by a poem of the same name by W.B. Yeats, which traces a spiritual journey and explores the concept of immortality. Buy it here.

The best-selling phenomenon tackles life's biggest questions in an appealingly whimsical package.

Most of the titles on this list conceive of A.I.-heavy futures. But of course there's also the western component of Westworld; to match that in a book, you could scarcely do better than this Pulitzer-winning classic. The frontier epic gorgeously realizes a dusty Texas town where outlaws, heroes, and everything in-between converge. Buy it here.
