Books by James Rollins are not only incredibly enjoyable to read but are also loaded with interesting history, facts and science. I really like how at the end of the book he explains what parts of the book are rooted in fact and what is fiction. This book was another wild ride with the Sigma Force team.

The Demon Crown is book thirteen in the Sigma Force series and let me tell you that this is a favorite series of mine and I have read every book published! And, the series keep going strong with its mix of thriller, science fiction, and adventure. One thing I always find so enjoyable with the books is the history lesson you get. Like in this book which started with Alexander Graham Bell traveling to Italy to steal James Smithson (founding donor of the Smithsonian Institution) remains. Yup, true story. Quite a fascinating tale.

But, what has James Smithson remains to do with this story? Well, you see he discovered something that could change the course of history and pretty much unless destruction on earth. And, of course, now someone has managed to release it. And, it's up to the Sigma Force to stop it. Without spoiling the story too much do I just want to say that there is a deadline of three days before everything is too late so they have to hurry to solve the riddle that Smithson left behind and find a "cure".

As usual is the book thrillingly good, and this one is storywise better than the last book. The threat to the life on the planet felt acute especially when the story in detail revealed what could happen to the human body if the threat that has been realized would infect. Trust me, I was like "shoot me" if that would happen to me! Personally, the only drawback was that the story now and then got a bit "scientific". I'm more a history fan than science so I prefer when the characters travel over the world hunting information than stories taking place in a lab. But, that's me. Other than that was the book truly great and I can't wait for the next book to be released!

I want to thank the publisher for providing me with a free copy through Edelweiss for an honest review! ( )

I will never look at a wasp the same way again. ( )

First things first, I knew what I was going to get from this book before I started it because I’ve become used to this series. So, it was a good read and met my expectations. It felt nice to meet some of my favorite characters, whom I have loved for over a decade now.
I always enjoy the action sequences in the Sigma Force series and they were awesome here too.
I absolutely loved the descriptions of the city of Tallinn (especially it’s Library) and the Salt mines in Krakow. Mr. Rollins always manages to make me want to visit the places he so wonderfully describes in his books.
But the book also dragged at a lot of places and I skimmed quite a few pages. I was not disappointed, but I hope that one of these days, my expectations will be exceeded too. ( )

Marginally better than The Seventh Plague, mostly because of the great settings in Hawaii, the Balkans, and Wieliczka salt mine in Poland. This series has stagnated, with little character development, and most new ones getting whacked. As payback for Hiroshima, Nagasaki, and the death of his beloved ninja, an aging Japanese pharmaceutical magnate looses a nightmare invasive species after liberating it from its amber cage for several millennia. The Sigma Force is divided into teams to battle the scourge, and an old adversary makes an appearance; however, the uncharacteristic and pivotal switch of sides, as the walls starting crumbling, made no sense.
