Five stars is frustrating. I'm inclined to rate is comparison with others in its genre (very broadly speaking), thus four stars, but if I were to compare it to other books I'd have to give it three at most, probably two but that feels so very low. It was good, not great, and succeeded at what it was trying to do.
I read this as a free e-book. It was a pleasant way to spend some evenings.
The mid-twenties protagonist is growing up and also inclined to imagine a bit too much, which is a good way of writing a low-stakes "cozy crime" novel. The genre-driven nature of publishing seems to push books into either crime or romance, but neither are truly central here. Instead it's more about the young woman, her aunt and creating a life worth writing about.
