Was this an early book/series written by this author before he learned more of his craft? As many of the other reviews point out, there are scientific, technical and other types of factual errors that are an immediate turn-off to the well-informed reader. Most sci fi readers are in fact very knowledgeable, and most will research with a quick online search any information that is presented as fact to be sure that they understand it. Meteors don't behave as this meteor behaves, but Calvert tells us it is not a craft, but an asteroid. Can't change the laws of physics. Can't hunt for Spanish galleons off Hawaii because they didn't sail there and you can't rewrite history. When you write about a topic, you better get the most basic as well as arcane facts right. Readers won't tolerate magic unless you are writing fantasy. Secondly, the three plot lines are confusing. Yes, this is meant to be the opener of a multi-book series, but you can't give some indication of how diverse story lines are going to join up at a later time or your reader is left totally confused. Grammatical errors should not exist. Not with apps that fix grammar, not with human editors. This is clearly a book in which the plot line determines what the characters are going to do in order for the story to unfold, as opposed to events occurring as a result of character driven choices. Many good books are plot driven. But to ignore any attempt to make the characters act as individuals as opposed to collections of stereotypes is a real let down to the reader. You can't root for a two-dimensional cardboard cut-out of a hero or heroine. And please stop infantile sexualization of female characters. Women buy a lot of books. Remember that. I am not sure I can continue the series. If this is what earth is like, then I would rather see it turned to rubble.
