A Good Day to Pie by Misha Popp
I loved A Good Day to Pie. This is the second in the series featuring pie baker Daisy Ellery. I would suggest reading the first, Magic, Lies, and Deadly Pies, before starting this one. Daisy has magic that she can bake into her pies and she most often uses that skill to kill abusive men.
This time around Daisy has entered a baking contest, apparently like the Great British Bake Off which I've never seen - I've watched enough competitions on the Food Network to get the idea though. It turns out that one of the judges is a man she is supposed to deliver a murder pie to after the contest, which is a bit worrying. It becomes an even bigger problem when the man ends up dead before she can even give him the pie. Now she needs to find out who killed him and whether there is any way the cops might be able to connect Pies...
