Here are the covers for Livia's two new mystery novels that will be out this fall. THE PUMPKIN MUFFIN MURDER, the latest book in the Fresh Baked Mystery series, will be released on November 2. KILLER ON A HOT TIN ROOF, the third book in the Delilah Dickinson series, comes out a few weeks later on November 30. I've read both these books and think they're great. Of course, I'm hardly an unbiased judge, but you can trust me on this one.
