Great plots, lovely use of English, lovable characters.
Format: Kindle
This series is a joy to read for lovers of the English language. The characters are interesting and/lovable. My family on my mother’s side lives in Florida and growing up I was certainly subjected to the mores and traditional thinking of the South, which did not help me at all in life, so the exposure to that culture raises an exasperated smile in me. For someone like me who loves to read the fact that the books are longer than normal for cozy books makes me very happy.

This would be a terrific book even without the mystery!
Format: Mass Market Paperback
The book has so much literary merit, that it could be placed among the novels. However, the excellent mystery plot also wins it a place among the mysteries.
Haines creates characters who are memorable and vivid and places them in the Mississippi Delta town of Zinnia (I'm kind of reminded of the movie "In the Heat of the Night"). Sarah Booth is living in the ancestral home -- she is an orphan and an only child, the last of the Delaneys -- but is about to lose it, because she is destitute despite her social credentials. Her only company at Dahlia House - the antebellum house -- is the ghost of a slave, who appears in a variety of outfits and "encourages" Sarah to get to work reproducing.
In an attempt to earn some money, Sarah takes on the task of trying to get to the truth of a scandal from 20 years ago in which first a leading citizen and then the leading citizen's wife die in some very questionable accidents. THe two young offspring are whispered to have something to do with it, and Sarah's client wants to find out if Hamilton the Fifth is as bad as rumors have it. Hamilton the Fifth is a romantic interest worthy of Evanovich -- and did I mention the book is often funny?
Sarah is stirring up some dangerous memories and some deaths start to follow.
I really loved this book and can hardly wait to read the next in this series and discover what happens to Sarah.

Southern Melancholy
Format: Kindle
On the plus side, "Them Bones" delivered on transporting me to the Mississippi delta (how do you stop typing Mississippi? it just begs to go on endlessly, like banana). I was there in the South and in a small country town. Brilliant on setting, which is what I like in a cosy mystery.
The mystery itself took a while to settle in and then, well, I guessed the plot. That meant instead of suspense, I plodded through having my hunches confirmed. But if I'd been charmed, that wouldn't have mattered.
This is not a negative review, but I'm heading towards the big problem I had with the book -- and I think this may be related to the fact that I was so busy and looking to enjoy some simply, happy downtime.
"Them Bones" has humour and a southern feel, but it also struck me as melancholic. And melancholy I did not need. For others (and maybe for me at a different time) that sense of mourning and tangled history might resonate. But it was a heavy load for the plot to carry.
Three stars for a solid read.

Expect to be hooked
Format: Kindle
Great cozy mystery with characters that become friends in a story that is great 'light" reading for an escape from the usual serious stories and politics on the news. Some laughs, some scares, some regular activities to fill out the characters are in good balance for the genre.

Not Really a Daddy's Girl Any More..but can sure know how to use it..
Format: Mass Market Paperback
I have at least five of this series that have been in the TBR pile on the bedroom bookshelf..What was I thinking? I absolutely loved this first one for many reasons.One being the rich content that makes up this book, as well as the main protagonist, an Ole Miss Southern Belle, Sarah Booth Delaney, a bit of an outlier when it comes to her former stereotype in the Daddy's Girls(DG's) clique...which is what endears me to her most...never, ever typecast someone as starting out as cut from the same cloth when circumstances aide in their character development..a definite asset in this case. Independent and also in need of money to save the Family home, Dahlia House.and in no hurry to give up her independence for marriage but will consider some stops along the way..when all her former buds have married for economic security rather than love. The dot of on the 'i' is a several generations removed ghost in the form of Jitty..her great, great, grandmother's maid who provides insights and caustic humor throughout. Thrown into these dire circumstances, she latches on to the opportunity to become a Private Investigator. Add a transgender character who happens to work for a local paper in the gossip area, and Sarah Booth is off to the races. Sprinkle in an alleged, physic who is a mainstay of her life long and still successful "DG's, Tinkie, " a murder mystery, a sibling in a psych ward(comfortable of course) a sheriff, and you have all the ingredients of a good ol moss draped mystery. You gotta love it..I know I did.
