Invisible Things

Things move at a good pace and enjoyed the longer passages and less dialogue in the first half specifically because of the writing - it' s clear, it flows, it isn't too much prose and has a solid mystery, characters, and readability.  Unexpectedly turned into an alternate future-esque political thriller in the second half, which actually made it a bit more interesting, but really only started to address the title matter in the last 75 pages.  The power jockeying and shady practices towards the end were a timely parallel to current real world challenges, but disappointed with what felt like an unfinished conclusion and more like a cliffhanger.
