This is the third of the Company stories. I hope to get to number one soon.
In any case, this one is really good. Mainly, not a lot happens. The bulk of the book is about a few of the Company cyborgs working in 1862 in what will later become Hollywood (thus the title). They are mainly there to collect specimens of things that will soon be extinct. We follow them as they do their jobs, try to avoid boredom, and get into difficult situations with mortals. Mendoza is a good point of view character, as she's fairly misanthropic but also a keen observer of the people around her.
Recommended. Also, you should probably read it in order, unlike me.
