While the plot summary of this book sounded promising, the book was, overall, a letdown. My biggest problem was that the writing was very flat, simplistic and not engaging. There were also plenty of noticeable grammar mistakes that were very distracting. I didn't look forward to picking this up again nor did I fight to keep my eyes open so I could find out what happened. Katie is quite one-dimensional, as is her mother and most of the 2008 storyline. In the 2008 portion, much of the formal language used is not believable, as most teenage girls don't speak like Katie does. This makes her hard to relate to and I also found her just plain uninteresting. The Celtic portion of the story was somewhat more enjoyable to read, though still not great, and Mortunda is, while not always entirely believable, an appealing person to read about with complexities and a unique and exciting connection to the supernatural. Also, the spiritual leaders are unusual with a few skeletons in the closet, just waiting to be unearthed, and this adds uniqueness to the overall plot. A strong point of the book, in the midst of very weak points, is the historical connection between present day and ancient times. The description of the tribal way of life is realistic sounding and the overlap of the geographical location is a very cool tie-in. Unfortunately, these are the best things that can be said for The Jewel Keepers, as it was ultimately written with mediocrity and a plot with potential that wasn't recognized. I will probably not recommend this to others and I will not read the sequel.
