Mixed feelings about this book. I like the titular character as it's great to have leading PI's who are neuro-diverse (see the great "IQ" series of novels for another engaging character.) I like her backstory which I learned from the three Bill Hodges novels. I'd not read the other, more recent, series in which Holly and Barbara Robinson appear. And I don't think I will read it now as there's quite a few references which apparently spoil the climax in at least one of those novels. On the negative side, I don't like mysteries where the identity of the villain(s) is immediately known by the reader. While this gave intense insight in to their heads in this instance, I feel much more suspense could have been built. And then there's the cannibalism - which doesn't remain a mystery for long either. I think it was handled mostly tastefully (pun intended) - except for one scene late in the book which involves lines drawn by a sharpie - which was jaw-dropping for me. Lastly, the "twist" which leads to the climax was telegraphed a mile away. NOTE- I was disappointed in the audio version of this novel. I'd listened to the outstanding reader for the three Bill Hodges novels. Although Holly was a secondary character, he gave her a voice which illuminated her uniqueness. While having a female reader for "Holly" makes sense, I thought she gave Holly a flat, uninteresting and often tough to listen to voice. Overall, a good, mostly engaging story, but lacking in a few key areas.
