Publisher's Summary

It starts with a thunderous crack and a flash of light. Screams come next. Then the hunters. With a staccato flicker, light disappears and everything within a hundred-yard radius goes with it. All that remains is a massive crater where a chunk of the world has gone missing. As the deadly phenomenon repeats and expands amidst the world's most densely populated cities, Jack Sigler, Callsign: King, and his black ops team take action. But the team is broken, spread across the globe, and vulnerable.

Scrambling to make sense of the violent disappearances and fighting to reunite, the team comes face to face with an otherworldly enemy. Taking the battle to the ends of the Earth - and beyond - the team combats a savage enemy whose centuries-old plan for mankind has nearly reached fruition. If they fail, the planet will become little more than a fully stocked food cache.

another great book

I love the entire series. Jeremy Robinson does a great job keeping the story going from book to book. It give you something to look forward to each time you finish, ready to get to the next one. And Jeffrey Kafer is awesome. Always love when he reads.

I'm hooked!

I finished this past novel in a day. I can't get off the adrenaline boost I get from listening to it while I do my daily chores and as I ride around town. I can't wait. I must get the next one. NOW!

Excellent story

What did you love best about Ragnarok: A Jack Sigler Thriller?

Another awesome adventure with the Chess Team!!! It has everything you've come to expect with one of three books and I am very glad I read all the novellas between the last full novel and this one. If you haven't, you really should. Excellent book!!

Any additional comments?

Jeffrey Kafer has a fantastic way of bringing the book to life. I love his interpretations of the characters, especially Rook, who continuously cracks me up.

A must listen

I think this is the best book in the Chess Team stories so far. The team is back together, fighting other worldly creatures to save the world. I couldn't stop listening. Kafer is on fine form.

Jeremy Robinson does it again!!!!

Would you listen to Ragnarok: A Jack Sigler Thriller again? Why?

You bet..just to catch anything I missed the first time! Jeremy Robinson does it again!! From start to finish, an action-packed, edge of your seat thriller! The Chess Team members are called once again to combat a new terror that threatens the existence of man and takes the team not only around the world but into a new dimension. This one is a Chess Team fan must read!!
Jeremy never fails to create a story I can become completely engrossed in. His characters are not static but continue to grow and change with each new challenge. I have read each of the books in this series and I cannot wait for the next. So often in this genre reoccurring characters are stereotypes. Not in Jeremy’s books! As a woman, I love that he offers up strong female characters in his books. Not just kick butt..and oh they are, but wonderfully written characters I can cheer for! Then again… all of his characters walk right off the page!
Of course Jeremy’s imagination is rivaled by none! He never fails to create new challenges for this team that blow me away! Still wiping virtual white goo off myself!! As always he leaves us wanting for more. Grab a cup of coffee, a cozy spot and settle in for a great read!

What other book might you compare Ragnarok: A Jack Sigler Thriller to and why?

Honestly there are a few I might compare it too..but I won't because his character development is so much better than most in the genre! I was so thrilled that I did not find static characters in his work!

Which character – as performed by Jeffrey Kafer – was your favorite?

Hmmm...I love Queen..but I think Bishop is the one I enjoyed the most in this book! Kafer did a wonderful job with the accents!!

Was there a moment in the book that particularly moved you?

Perhaps at the end..but I won't give that away!

Any additional comments?

Cannot wait for the next one!!

One of my newest favorite authors

I've listened to many Jeremy Robinson books over the last few month. None of them have disappointed. I'm glad he puts out nearly 4 books a year, which doesn't make me wait long for a new one. His imagination is incredible.

A beast's garden

I still remember when I bought the novel and hearing it in audio was a true experience that better it even more. The story was truly interacting has it links different books that highlight the author world building skills has kept on the rise like a roller coaster of action. Do I do hope we get a future novel we get to battle fenrir aging!!!

As usual....

As usual with these stories about Jack Sigler at some point we start star trekking with the plot. Oddly, it works and the stories are interesting. I don’t mind listening to them since they tend to become something that makes you say “ where are we going with this?”

Struggled with this one a bit

Don't get me wrong I am enjoying the series as a whole, I just found this one a little disjointed with too many threads going on. Little harder to follow than it needed to be. Lovely twist at the end though and I love the usp that every book ends on a cliffhanger to the next. Not bad, but I hope the next is slightly more cohesive.

crazy, over the top, unbelievable, AWESOME

Jack Sigler and the chess team are back at it. Such action and ideas would not fit in a blockbuster movie. Great stuff.
