Becka Johnson had been abandoned on the doorstep of a remote cabin in Chalcedony, Colorado when she was a baby. Now, thirty-seven years later, she has returned to Chalcedony to discover her identity, but she only finds more questions.

And what do either of them have to do with a shadow corporation that once operated a secret underground installation in the area?
