Rebel Belle

I have a big thing for Belles and the South (blame on Hart of Dixie) so when I first discovered this book I had to read it even though english isn't my mothertongue.
And I really loved it. Until the last pages.
It is an amusing, full of suspence book, even though I found the storyline a little slow in certain points but it's definitely a good story and I enjoyed a lot.
But the beginning and the end are the most important parts of the book and the end was totally disappointing.
What was the point of Saylor dying and passing her powers to Ryan??? It was surprising and a heck of a plot twist but I didn't like it at all.
And what about Bee? She's taken somewhere by Blythe and Harper does nothing about it? But who cares, she has two boys at her feet.
In the end, it is a lovely book but it left me a little disappointed.
