Enjoyable, but with a few problems...
Overall, Lindsay McKenna's Unforgiven was an enjoyable read for me. I particularly liked the heroine, Calen Hernandez. She was strong, intelligent and independent, not a delicate waif waiting to be rescued. The story centers around two Warriors for the Light/shape-shifters, Calen Hernandez and Reno Manchahi, brought together by destiny to find the first of seven emerald spheres that make up the Emerald Key necklace. This necklace, in the hands of the Light, will bring about 1000 years of peace on earth. However, dark forces are also on a quest for the necklace to produce the opposite effect.
The problem is that this is not a stand-alone book; it mainly sets the foundation for the rest of the series to come. There is a lot of background information given about the prophecy of the Emerald Key, which is fine if you intend to read the rest of the series. I would have liked less background info and more written about the relationship between Calen and Reno. Also, I am a little confused about the book's title, as the emerald the two characters discover is the sphere with the power of forgiveness.
This is the first paranormal romance in the Silhouette Nocturne line. The paranormal elements were interesting (shape-shifting, powerful emeralds), however, the romance was light. It was a quick read, as the writing style was not complex. This is the first book I've read by Lindsay McKenna, so I can't compare the writing to her other works. It was enjoyable and worthwhile if you are planning to read other books from the Warriors for the Light series.
