All We Hold Dear

After the murder of her grandmother, Dora Baskin inherits her home, a 172-year-old log house in Manitou Springs, Colorado. Was the murder a random act of violence, or something even more sinister? 
 
With her new friend, Shawn, Dora gradually finds the answer in a handwritten account of one of her ancestors, Isadora Byrnes, a nineteenth century Englishwoman taken in by a Cherokee family. In the pages of this journal, they learn about the secret organization which spent decades pursuing Isadora Byrnes to America, beyond the Trail of Tears and into the Rocky Mountains, seeking to acquire the mysterious silver artifact she possessed. 
 
They also find that this organization is still around, they still want that artifact. 
 
And they think Dora has it.
