Night Shall Overtake - Kindle ebook by Michael R. Collins

Twila is a surly shapeshifter and seriously underpaid as an assistant to a private detective.  She works in a city where being a shapeshifter isn't even the weirdest thing.  Populated with walking nightmares and Lovecraftian horrors, it's underbelly just might try and eat you.  These creatures aren't hiding in the shadows (usually) but run the local shops and strive for middle management. What should have been a simple missing person's case has turned into a complete snafu. Instead of just find her and collect their fee they jauntily go off to the worst possible part of town: The Dark Quarter. Now Twila and her compatriots must not only face down the most evil things around, they should probably be polite about it.
