I loved Mind of my Mind and Wild Seed, was only ok with Patternmaster, and don't know what to think about Clays Ark, since it was strong overal before the ending ended up being a mess. In general, this is a series worth reading. All the books are so different from each other but still manage to build on each other in some way. If you want to experience a whole new dimension of worldbuilding, creating and showing a history of a fascinating society, read this series. If you don't like of of the books, you might still enjoy some of the others, since the characters, setting and periods are totally different each time and I would even put them in different (sub)genres. Since no one would read an in-depth review of 4 books here, I will leave a link to my blog, where I will discuss them over the next days, if you really care check that out. https://steemit.com/books/@dedmops/thoughts-on-patternmaster-octavia-e-butler-s-seed-to-harvest To everyone else: Just get this book, it's mostlly the price of one quality paperback, so you got your moneys worth if you only liked one already. It is more wholesome than other series are able to and it will definetly be interesting at least.
