I see what you mean. Kibosh isn't my favorite but that's because Kibosh focuses too much on Terry's sex life and not enough on his usual work. And since he's on most of the photos, they obviously weren't taken by Terry but his assistants actually shot about 85% of Kibosh
Do you more information about this new book?
about the new book we must ask Ali, she is here on the board, I made a post on her, just ask, she could reply or even post some anticipation photos, didn't she already posted one? or is it from a past book? you must know, as it looks you already own almost all of Terry books

take a look if you have something more of her and scan

she could have more reasons to reply at your questions if you post her photos in her thread

from a certain point of view sex life could be good, but Terry as a subject is not interesting, at least not for me, I guess some girls or boys could be very happy to see his c@ck that often, but even if you are in to it, always the same subject is boring, he is not even Rocco Siffredi!

I think I saw Terry and Rocco side by side in one shoot, but at least that was ironic

that is what is missing in his book, if you can't make "art" photos make them at least funny,
"look at me, I have a big c@ck and I f@ck girls" as the main theme of a book looks a lot childish.
about his "unskilled" assistants, Cellina von Mannstein was not that bad (she makes snapshots with more irony than Terry), but she now works for her own, so I also guess Kibosh results are due to a missing good assistant photographer ...
