Quantum by Patricia Cornwell

 Q in my A-Z of Fiction Titles is Quantum.  

The blurb says:

On the eve of a top secret space mission, Captain Calli Chase detects a tripped alarm in the tunnels deep below a NASA research center. A NASA pilot, quantum physicist, and cybercrime investigator, Calli knows that a looming blizzard and government shutdown could provide the perfect cover for sabotage, with deadly consequences.

As it turns out, the danger is worse than she thought. A spatter of dried blood, a missing security badge, a suspicious suicide—a series of disturbing clues point to Calli’s twin sister, Carme, who’s been MIA for days.

Desperate to halt the countdown to disaster and to clear her sister’s name, Captain Chase digs deep into her vast cyber security knowledge and her painful past, probing for answers to her twin’s erratic conduct. As time is running out, she realizes that failure means catastrophe—not just for the space program but for the safety of the whole nation.

 I don't think I've read any of Patricia Cornwell's books before, though I'm well aware she is a prolific and well-revered author.

The thriller side of this book I enjoyed.  Trying to work out what is going on with Carme as well as finding out why there was a suicide and the mystery of the tripped alarm.  However, I didn't see the point of the NASA background, the rocket launch and all that side of thing.  I get that it's just the backing for the story, yet it seemed so irrelevant, that the story could have been situated elsewhere and nothing much would be lost.

There is also no ending to the book.  I understand the idea of ending on a cliff-hanger, but I much rather books that have some sort of ending, with an epilogue/final chapter that introduces the cliff-hanger.  This book, however, simply doesn't end.

Overall, I'm just disappointed by this book.  Reading other reviews however, have shown me that even Cornwell fans didn't like this book, so that gives me hope should I ever decide to read one of her other series.

I've put the next book on my wishlist, just because I want to know how the story ends, but there are a load of books on my wishlist that I will be buying before the next one. 
(For new readers to my blog - hello, and welcome!  After discovering I had nearly 1000 unread books on my kindle [I love a freebie!], I'm now working through them, refusing to buy any more books until these are read and down to a decent level.  I'm getting there, with only 660 still to go, lol.  The only exception to my no-buying rule, is if a book is so amazing, then I do tend to buy the rest of the series and live in that world for a week or two...)
