This is the second disappointing novel from this author for me, so I am quite done with him as a source of entertaining reading from this point onward. This is described as the second in a trilogy, but the first in the 'trilogy' is also described as a sequel to a previous novel so how this works as a trilogy rather than a quadrilogy or even a series is a mystery.
I made it almost half-way through, and while I was initially interested in how the story would pan out, the writing was so bad that it felt like I was reading some middle-grade school essay. Add to that the fact that it was read by Stefan Rudnicki (again), a reader whose voice just grates on me and it was not an appealing listen.
In my review of Bova's Transhuman I said that Stefan Rudnicki reminded me of the kid in the Home Alone trilogy, who in one movie records his own voice on a tape recorder, then slows the tape down to make it sound adult. Stefan Rudnicki sounds exactly like that, and it was really hard to ignore that and focus on the story. Nothing's changed in this outing.
Had this novel been written in the forties or fifties, I can see how it ended up as it did, containing genderism and racism and other isms, but it was released in 2016, so there's no excuse for this kind of juvenile, clueless writing, especially not from a supposedly seasoned and respected name in the genre. Note that there is a difference between this and in having a racist or genderist character in a story who makes inappropriate comments. There are people like that, so it's fair game to portray them in novels, but for the writer himself in his narrative to do the same thing is unacceptable.
Women were routinely reduced to eye-candy in this story, with not a one of them having an important role to play, and the senior female crew are portrayed as shrill harridans. One of the main characters was an Australian aborigine, and Bova never let us forget how short, round and black he was despite the fact that the average height of such people is about five foot six, which is not exactly pygmy-sized. The only amusing thing in this was that the reader, in trying to pull off an Australian accent, made this guy (whose name, believe it or not, was Littlejohn) sound like he was South African.
Those issues were enough to can this novel, but the problems did not stop there. This novel was purportedly hard science fiction, but the science failed, being completely fictional. According to the inane blurb, "A wave of death is spreading through the Milky Way galaxy, an expanding sphere of lethal gamma radiation that erupted from the galaxy's core twenty-eight thousand years ago." Humans are supposed to be spreading-out to aid other planets with intelligent life to avoid being wiped out. Given that our planet is only 25,000 light years from the galactic center, the radiation has already passed Earth, so how humans hoped to get ahead of it when it's moving at the speed of light is a mystery. I assume they have some sort of faster-than-light travel available to them, but very little was said about that.
They are apparently putting up some sort of shield which will save the planets. There's no reason they could not simply do this and move on, but instead, they've spend a year 'studying' the Mithra system and its three life-supporting planets. There's no explanation given for this lollygagging. three planets here support life, but it's significantly below the human level of advancement, and one species lives entirely underwater, so it would not have been hard to have installed the protective devices and gone unnoticed, without any contact with the inhabitants, yet here they are dicking around! It makes no sense. Since about 14 feet of water can stop gamma radiation, the underwater inhabitants are perfectly safe, so what gives?
More damningly, this radiation has been expanding in a sphere for almost thirty thousand years. According to the inverse square law, the density of the radiation, and therefore the danger it represents, has to be so low now that its impact on planets would be considerably reduced, if not negligible at this point. Bova never tackles this. Neither does he seem to understand the difference between philology, the study of written language, of which there is none to be found in this solar system, and linguistics, which is the study of language. Nor does he grasp the distinction between anthropology and sociology.
Worse yet, the main character, Brad, is such a special snowflake as to be thoroughly nauseating. He's credited with coming up with 'brilliant' ideas which are in practice nothing more than common sense and certainly something many others would have thought of, yet he's portrayed as being almost magical to think these things up! There's this dumb-ass computer which has all manner of useful information but which apparently was never programmed to volunteer information - although it actually does do so all the time. It's the dumbest AI ever, and the humans around it even dumber in not knowing what questions to ask it. Except for Brilliant Brad, of course.
Additionally, two of the planets in this system they're studying are in eccentric orbits and this author expects me to believe that they pass so close to each other that their atmospheres mix, yet while he talks about storms and tidal waves, he says not a word about the inevitable cataclysmic, life-destroying earthquakes which would occur if they were really that close! In short, Bova is in way over his head here and needs some serious schooling in physics, biology, evolution, linguistics and sociology before he ever writes another sci-fi story along these lines. I'm done with him.
