Discount Armageddon by Seanan McGuire
Thoughts so far:
This book reminds me slightly of Jeaniene Frost's Night Huntress series starring Kat & Bones. I don't think it will be too similar since there are some crazy talking mice so far. The main character is a woman who hunts down monsters. In the first part of the book she is in a bar dancing around trying to spot the ghoul that is killing people. She finally spots him and follows him out only to start a fight with him.
Look for tomorrow's blog post for a teaser of this book.
