    Just finished up Bone Labyrinth…awesome! I’ve enjoyed all of the Sigma Series, but I have to say this one is my favorite. Well done, Mr. Rollins.

    I could not put this book down. I need another Sigma book. Maybe I’ll just re-read all the old ones–they are all so good.

    In the end 10 years later Joe Kowalski is not with Dr. Crandall when she goes back to see Bakko. She twists her diamond ring but I did not get a good impression on what happened to Joe. Did he die? Did they just marry and divorce? If he died, I will be sad to see him go as I quite enjoyed his character. Please let me know.

      Hi Shelley,

      As will all my adventures, there is a plan. Stay tuned for the next Sigma Adventure, The Seventh Plague

    I just finished reading the Bone Labyrinth, and like the rest of your book I enjoyed every pages of it, couldn’t put it down. The very end though is something
    I never expect. Please tell me you’re not going to kill Kowalski. Loved every character of Sigma, since I’ve read every single book. I literally cried at the
    end not knowing if I’m reading or understanding what happened. I just can’t picture either any one of them not included in the book, it’s not going to be the same. I would be one of your happiest fan if read your next Sigma book and Kowalski would be there.

    I’m wondering the same thing about Joe Kowalski. At the end of the book when Maria sees Baako for the last time, she has a ring on her finger that “brings joy and pain.”
    She had a story for Baako about Joe, but it was never told. I certainly hope he’s around for more Sigma novels, I really enjoyed him having a softer side in this book.

    Please don’t kill Kowalski. The guy is a legend of brawn meets more brawn and dry humour! I’ve read your books since 2005 or 2006 and at 33 I’m still loving them! Nice work Mr Rollins 🙂

    Hey Mr. Rollins,
    You may not check these post anymore but figured why not post anyways. My brother introduced me to the Sigma Force Series, and I must say… Well done sir! Been a good while since I have looked forward to picking up a book when I got home from work. Just finished the Bone Labyrinth, and went to order the 7th Plague, seeing I’m a little early, but just barely. Looking forward to it.
    On a side note, my wife makes the best peanut butter chocolate filled cupcakes you have ever had, like seriously man, to die for. I would be willing to strike a deal… Say a dozen devishly good mini cakes (totally normal accepting food from a stranger on the line I know)… And you don’t kill off my favorite demolition expert within the next 10 years? Eh?

    I absolutely loved this book. It was my first to read and I am hooked. I also was waiting for an explanation of Joe Kowalski’s where abouts. But you answered Shelly’s question above. Can’t wait for the next instalment. Thank you so much.

    Just got done reading Bone Labyrinth; little bit behind the reading curve right now because of life. I have the Seventh Plague on hand though. Just hoping all goes well with Kowalski. He’s an absolute staple Sigma member…
