City of Angels

Ms. Shannon's character is the most clearly defined, as is to be expected as the book is told from her POV. I didn't find anything particularly inconsistent with the time period, but the book didn't feel like a history lesson - the language is clear and engaging. The cast of characters are introduced to us as our protagonist meets them, and we learn things about them as she does...the flow of the action and dialogue felt very natural.
The actual case was interesting, adding a bit of mystery to the story, and I found the book very hard to put down.
