Book 5 of the Time Quintet. This is the final book in the series and this time we follow the daughter of Meg Murry. This was a little darker and yet still a great read. She is whisked back 3000 years. Dealing with the people of their valley. We have betrayal and human sacrifice and ancient and modern beliefs all wrapped up in one. This was a very nice ending to the series, but like life the series could have continued on.
