- A Wild Sheep Chase by Haruki Murakami
A strange man is coerced into hunting for a sheep, which ends up being the least-strange part of his adventure. - The Little Prince by Antoine de Saint-Exupéry
- Bellwether by Connie Willis
A charming story about what causes fads and how to predict them. The answer lies in sheep, of course. - The Android’s Dream by John Scalzi
The sheep in this novel is not exactly what you would expect. Suffice to say, it talks and has other humanlike attributes. Any more would give up the book’s most accomplished twist. - Independent People by Halldór Laxness
Wikipedia calls this an “epic” novel, but I must respectfully disagree. It is a mostly depressing tale of sheep farmers in Iceland; its unexciting tone seems to accurately reflect the boring lives they lead.
A common theme in these works is sheep unintentionally manipulating the lives of people, by pulling them along into paths they did not expect. This is especially interesting since sheep are generally associated with following, not leading.
