Query: Horrible, Disappointing ending ruins the book

This book had a very good plot. The details concerning the history of the native people and the region could have been less; it kind of took away from the direction and the pace of the story. The book was good until the ending, which completely made me feel as though I wasted my time reading the beginning and the middle. It was as though the author's deadline was upon her and she wrapped up the ending all neat and packaged. Absolutely ruins the book.
