Bellwether by Connie Willis Statistician Sandra Foster and chaos theorist Bennett O'Reilly are brought together by a misdelivered package and urged into their own chaotic world of million-dollar grants, unlucky coincidences, setbacks, and eventually the ultimate answer. This is one of Willis' earlier books and not so much science fiction as the how scientists discover the answers in the most surprising places and ways. I love her books so much and it was interesting to read this much shorter book of hers as her newer books are very long but so good.
