Thank you @prhaudio for a copy of this book. 

Told in dual timeline with 1909 with Ollie and Nessa running away to runaway to escape their life and into the mountains of Oklahoma. The other time like is set in 1990 with Valerie, a park ranger that discovers a long ago burial site and starts investigating. 

Both of the timeline kept me interested. Ollie and Nessa was so resilient and met some other children along the way and helped each other. 

I appreciate how much research was done for the story and how Wingate tied the two timelines together. 

The story is told by Christine Lakin, Dan Bittner and Jenna Lamia and they all did a great job with the narration.
