This short story started off very strong. The main character is an astrophysicist whose colleagues consider untrustworthy due to a past problem that is alluded to but never specified. His wife is the head of SETI and well-regarded, but she is dying (cancer?). The stars are slowly disappearing from the sky. It seemed like it was going to be a moody, introspective soft (in a good way) science fiction story.
Then an alien shows up, tells them other aliens are coming to kill everyone, and, to put it bluntly, all hell breaks loose. Beginning at page 26 the story went downhill badly. The latter portion of it felt rushed, and was in desperate need of proofreading. Based on this sample, I'm not at all interested in reading the author's "first debut novel" that is to follow.
