I always enjoy Mike Tufo and Trip, then the twists and spins that keep my head reeling. Sometimes I’m not sure I can keep up! This one was another good edition, but, I need a happy ending soon!

Not a continuation of a Shrouded World but a new spinoff series. Great new story with new characters.

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.

Watching paint dry is preferable then listening to the Jack walker parts, Talbot and Trip as always are the only reason I continue to listen to this series. I’m not sure how there is a huge following of this Jack Walker character, but I guess even potato’s need something to listen to.

Why jack walker, why???

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.

A must listen

I’m in love with this series. I’m not at all familiar with John O’Brien, but I have read all of Mark Tufo’s books. I guess Mr. O’Brien has a new fan!

I don’t want to spoil anything, so I’ll stick to these few words: Mind Blown.

Excellent. Again.

Now that one problem is solved time to go fix another. I've enjoyed both zombie fallout and a new world series. This is a good mix of both. With New enemies to face, problems from jumping dimensions, twists turns and then there's Trip.

Two great authors
