My feelings on this one are.... Complicated. Hooey. 
 On the one hand, some of my feelings from "Litany of Earth" haven't changed, such as being a little annoyed Ms. Emerys took the black and white approach by making the Deep Ones basically completely innocent victims of the 1920's raid rather than making these two cultures have legitimate gripes with one another. I forgive her a little of her softening the Deep Ones by having them actually show up though! Which was neat. 
 Most people say they liked the "Litany of Earth" novella better than this book, and I can see why. This book does drag, and if you don't care for descriptions of esoteric books or the characters themselves, this book will be quite boring. The book oddly speeds up right at the very end, I think when the author realized she needed do something to wrap things up since nothing had really happened throughout the rest of the book. Ms. Emerys mentions how she had only planned on writing the original novella, and it shows in the book's pacing. 
 The virtue signaling was quite grating in the beginning, with how often the main character has to point out how she doesn't subscribe to any of those nasty -isms. Oh, and if you are a white male, you are going to be antagonistic in some way: female students all have more potential than the male ones, female librarians are more helpful, male government agents are bullies, etc. You get the drift. The only males who are allies are blood relatives or gay. Not even kidding. 
 But despite all of its problems, I enjoyed myself more with this than the novella. And I think it has to do with the prolonged time with the characters. Emerys was able to spend more time with a novel's worth of story to allow me to care about the characters, and allow me to get used to her vastly different interpretation of the Deep Ones. Though I found myself sometimes wishing the book would speed things along, I became invested in Aphra's journey to rebuild Innsmouth. Though I think Audrey is the most interesting character of the lot. (view spoiler)[Mad Ones ahoy! (hide spoiler)] 
 So despite my eye rolling at some of the heavy handedness of the 'political correcting' of the original "Shadow Over Innsmouth" and the erratic pace of the plot, I overall ended up liking the book. I don't know if I could recommend it to Lovecraft fans, as it has none of his atmosphere, themes or original creations; merely using names of his characters and setting for the author's political viewpoints. But I have come to care enough about the characters that I will be reading the sequel; not for the plot though, as I can't say there's really much of one to follow. 
 Edit: Thinking on it some more made me dock 1 star off the rating. On top of the problems I mentioned before, the whole point of the book being to not believe in malicious unfounded rumors seems to fly out of the window when one of the characters is revealed to have a dark family history and everyone.... proceeds to view that character differently based on malicious unfounded rumors. And in this case it turns out to be true! So what was the point of making the Innsmouth people all flowers and rainbows when Ms.Emerys was just going to shift the authentic big bad boogeyman label to another group and have the resulting prejudice be justified...? Seems to undermine the whole purpose of this 'revisionism' to me.
