Bests & Worsts Reviews from Amazon

What a waste of time. First of all the characters are ridiculous, just your typical astrophysicist / astronaut / quantum physicist / SWAT team leader / detective...you know, an average "Joe". Talk about contrived. Then, to top it off, the book just ends, in mid-scene, with a "see what happens next in the next book coming out in 2020"! Not a spoiler, as there's nothing to spoil, there's no conclusion to the book to give away. Got it for free with Prime, and I still overpaid.
