I want it Wednesday

I saw this book in B&N and it caught my attention then I read some of the reviews on Amazon(don't do that cause I think some give away a few spoilers). Anyway, the book sounds cool.

Summary:
Fast-forward a generation. New Orleans, now called New 2, has been decimated by natural disaster. Nine prominent families have banded together to buy the city from the federal government; all that used to be New Orleans is now considered "beyond the rim," an area rumored to be riddled with supernatural beings and happenings. Enter Ari. Inexplicably abandoned by her mother soon after the city's fall, she is now a hardened 17-year-old living in Memphis. When she visits a sanitorium near the border where her mother spent her last days, her discoveries lead her deep into New 2. In search of information to help solve the puzzle of her origins, she soon realizes how intricately intertwined her fate is with that of the city and that it will be up to her to lift the curse that has plagued the women in her family for centuries. Darkness Becomes Her is part "Lightning Thief," part "Twilight," and part "Maximum Ride." Unfortunately, Keaton reveals the specifics of Ari's mother's delusion at the book's start, something if left uncovered until later would have packed a much greater punch. Yet, to write this title off as a predictable "been there, done that" experience doesn't do it justice either
