I specifically remember liking Rainbow Six around the same time and I liked his books until he started tag teaming with other authors which was probably around 2000?
Based on that I imagine his books from 1986-2000 are “similar” enough.
I recall liking it, but I read it in like the 5th grade so my standards were low (before that I’d been reading my mom’s terrible ‘caterer turned detective’ novels).
I enjoyed Clancy for a long time after that but at this point I aim more towards militaristic speculative fiction.
Dianne Mott Davidson’s books.
Don’t get me wrong, I loved them as a kid, and it was a nice way to transition to “adult” books but not really my speed anymore and I imagine if I went back I’d think they were “bad.”
