I actually like that aspect of her storytelling; I think the first couple chapters of the book are beautiful. My complaint is a little different - I think that following the main, present-day plot of the book for almost its whole length before learning why Saavik is doing what she's doing is annoying. The jumping into bits of backstory make sense, but the main narrative acts like a linear story, only to turn out not to be. And the story I thought she was telling was, in my opinion, better than what it was revealed to be.
Same here - having said that, a MWB story I have problems with is still a better read than most of the trek-lit output.
