The Charlotte Adams mystery series by Mary Jane Maffini. These are set in upstate New York, and the main character is a professional organizer. There are lots of great organizing tips in each of the books, and she has two cute miniature dachshunds. I wish Ms Maffini would write more of them!
The Lacy Steele mystery series by Vanessa Gray Bartal. Set in small-town New York, the main character is a freelance journalist-turned-entrepreneur. I love these driven young female protagonists who take on a huge project in order to save an historic building.
