Query: A Surprisingly Disappointing Book

A whole world where all people share the same beliefs or reality together - without question. This fantastic premise could have generated a number of intriguing scenarios. But the author tried to spice it up with the hackneyed themes of interstellar warfare, supersmart ancient aliens, technologically challenged natives and come up with a novel that leaves you totally unsatisfied. On top of that the Physics described is juvenile fanatsy. The author 's talents lie in divining how genetic engineering can alter society and people. Stick to that larger theme. Wonder if Mr. Nancy Kress wrote the novel and passed it on as his wife's.
