This is the first book of the series of "Sarah Booth Delaney Mysteries". I have read all of them and each one builds on the one before it. The characters evolve into complex beings that you get emotionally invested in. That being said, this is the weakest book of the entire series so far. From this point on all of them warrant 4.5 or 5 star ratings!
This is the only series I have recommended and re-recommended to other readers of mystery.
They are lighter mysteries, but a little heavier than cozy mysteries. There is suspense and always a little romance too. I won't give away the best parts though, you will have to read them for yourself!
