A's story, the next character B's, finishing out the cycle and then repeating ad nauseum till it all comes together in the end. This is okay once in a while, but a distressing number of recent books have followed this style like it's some kind of sacred convention of sci-fi. I can always predict whose turn it is, and if it's not a character I really enjoy, my eyes glaze over till I hit one that I've more deeply bought into. The great books are tales, the craft and structure transparent and simple. I'm not asking for easy reads.
Complexity has virtues of it's own.
But a relentless pattern of repetitive multi-threading stands out like a sore thumb. I guess it just lacks a certain cohesiveness and flow. Each chapter is an interruption of the story of the one preceding, and I'm getting a bit tired of it.
