Blackwater series by Michael McDowell
Stranger shows up
McDowell wrote a series called Blackwater that tells the story of a southern family's rise and fall, all due to a stranger who showed up in town one day.
Flood is in Alabama
When a deluge floods a small Alabama town, it leaves something more than river mud behind.....something unexpected.
The Flood is the first in a series of six books in Michael McDowell's BLACKWATER series. This was a fantastic start that had everything you could want to satisfy those that love Southern Gothic books, and leave you wanting to continue the series immediately. A strange woman, stranded by a flood, is rescued in town. What follows in this book is how she takes to life in town and sets about marrying into one of the richest, most influential families there. Elinor is a mysterious character that I can't help but like--both for what I've learned about her, and what I haven't yet.
Eye on the cover, flooded town
