great story but felt like half a book.

his story was just as awesome as everything by these two authors except that it seems to cut off abruptly, as if they literally decided to make one book into two books and just cut it down the center. no epilogue no build-up no climax just suddenly and without warning... ended... and that was it. still a great installment of the shrouded World story none the less.

Hate cliffhangers. Love this series

This was a great addition the the Shrouded World Series. Bringing in the “additions” Mr’s. Tufo and O’Brien did was pure genius. Can’t say more without major spoilers. What other series will you find a Devil Dog partnered with an AF JSOC guy and a stoner-savant?! And the “big bad guy” that isn’t a bad guy.....Oh, and guns! And intelligent prose! Mike and Jack mesh together beautifully.
Gentlemen, you’re killing me with the cliffhangers! I listened to this in less than a 24 hour period I was that enthralled!
PleasePLEASE finish and release the next installment most Ricky-tick!!!

Semper Fi!

A must listen

Loved the book, along with other Tufo and O'Brien books. The continuing story has me wanting more. John's, Trip, and Mike are wicked awesome characters.

The fun just keeps coming.

This is a great spinoff collaboration from Mark Tufo and John O'Brien. Every book in this series and the original separate series has been incredibly entertaining. There is plenty of mystery, action, suspense, mixed with many great one liner humor. If you have listened to the rest of this series, get this one, it will spin you in different directions and bring you back again. #Scifi, #humor, #action, #downright fun, #tagsgiving, #sweepstakes.

Yet another great story from 2 of my favorite authors. You know the book is good when I simultaneously hate you guys and love you guys at the same time.

This is going to kill me

I hate Tufo and O’Brien. The wait for the next book is going to kill me. Trip has become one of my all time favorite characters.
Please hurry and write the next book.

Just when I think.....

I don't write gushing reviews. I must say that I was hooked into this by the end of the first chapter and with all the "Trippy" twists and turns by the end....I read it again. If I owned Hollywood, the first I would do is fire Alec Baldwin, the second thing I would do is to film two epic triologies of John Obrians series and then Mark Tufos. Then a 3rd combining both.

A great turn for this series

I love the be direction this series has turned into. I really don't feel I can say much without spoilers but I found this book more harrowing and exciting than the others have been, and I thoroughly enjoyed the others. Trip continues to be incredibly funny and perplexing whilst Mike and especially Jack go through some serious difficulty and pain. Brilliantly written as always from Mark Tufo and John O'Brien and as ever, Sean Runnette brings the story and characters alive with his skilful narration.
