Title: The story was drowned in scientific complexity
Review: Hal Clement is very well known for his hard SF. In "Mission of gravity" (1954), he managed to write a story that combined an interesting storyline with good and comprehensible science. In the current book, he lacks both a clear storyline and comprehensible science. It is possible the science is comprehensible for a graduate in biochemistry, but I doubt it. If not intended to be a textbook, it shouldn't be that complex. The story is, though based on some interesting ideas, completely wasted in too many details.
