(No spoilers in this review)The characters quickly became, not characters, but friends I KNOW (I think Patty is my favorite). I got so involved, I texted a friend to exclaim. . . “OMG! You won’t believe what just happened to Bish!”I was told by someone who would know, that the techie-science type of info in the book is well-researched and factual (much of which was over my head, but it did not detract from the story at all, quite the opposite). The best analogy I can think of is Chess. The novice chess player (newer Sci-Fi reader) can still play the game (read) and enjoy it greatly. While the Master Chess Player (Sci-Fi expert) will appreciate all the techie-science factual information that will, I’m sure, greatly enhance the story for them.If you like to learn some factual science info with your Sci-Fi entertainment this book is for you, but, even if you are like me, and Sci-Fi isn’t your first choice, but just love a well-crafted, fast paced story with plenty of twists and turns this is an excellent choice.Fingers crossed the author is working on a sequel, because I want to know what happens in the lives of my new friends, especially Patty!No need to be on-the-fence about this one. Grab it, you will thank me later.
