Cozy Mystery books are totally a guilty pleasure of mine. I don't have to think too much while I read them and I love the themes and how easy yet enjoyable they are.
Which have you read?
These are ones that I've read, maybe you can find something new from my list:
The Flower Shop Mystery series by Kate Collins (fun fact: the town is based on the city where I work, near where I live)
Coffehouse Mystery by Cleo Coyle
Books by the Bay by Ellery Adams
I've also read some with the theme of knitting, more on coffee, and others, but I have to look up the titles and authors.
