Yeah, I tried reading the books and just could not get into book 2. The jump from cyberpunk noir to future military action was just too big of a shift for me and I lost interest. It's odd because The Expanse goes through similar genre shifts and that one didn't bother me as much because it was much more of a gradual shift and it still maintained a lot of the same cast. It has been awhile, but I believe Kovacs is the only character that remains from book 1 to 2.
