I love the Patternist sequence of books, so I definitely recommend them! You do have an option as to how you might approach them...either by internal chronology or by publication order. I read them according to publication order, so that means I started with Patternmaster, her first published work, but last in the sequence by internal chronology. A friend of mine read them by internal chronology and she loved it that way, so it's up to you. Patternmaster starts in medias res and presents quite a dystopian vision, and although bleak, it's a very interesting and fast-paced read. The rest of the books were [sort of] written as prequels that culminated with the future presented in Patternmaster. Her later books (earlier by internal chronology) were better written, but Patternmaster has a vibrant energy to it that I've always liked, very similar to the dynamism of Alfred Bester's Tiger! Tiger! (aka Stars My Destination), but a completely different tone. All the books (except one) are collected in the omnibus edition Seed to Harvest by internal chronology. The book that was omitted is only very peripherally related to the main-sequence Patternist works and the setting is not Earth. And all the books can actually be read out of order, even with the connections (one of my favourite features in a series or trilogy, that they don't need to be read in any particular order!).
