When a family of four goes missing seemingly in the dead of night, Blake Wilder and her team are called to find the young family and determine the reason for their sudden disappearance.

Change is the only constant in life. It’s a lesson FBI Agent Blake Wilder is having to learn all over again. Summoned to DC by a Bureau legend, Blake is excited, imagining big things on the horizon for her team. That excitement though, is quickly dashed as her entire world is instead, turned upside down and she’s left to pick up all the pieces.

A reorganization within the Bureau has stripped Blake of her command and the unit she’d given her blood, sweat, and tears to build, turned over to somebody else. In this new role though, she is given a case that takes her team to Colorado to investigate a missing persons case.
There she finds that nothing is as it seems. Blake is having to adjust to this new world and her new team members as she finds herself caught up in a web of international intrigue, espionage, and cold-blooded murder.

New enemies rise, and old adversaries come to the forefront as Blake and her team race to find a man and his family being hunted by a ruthless organization. The sands of the world are shifting beneath her feet. Nobody and nothing is what she believes and Blake doesn’t know who to trust.

With the lives of the young family on the line, Blake juggles the danger that surrounds her, the changes that she faces, and the perplexing mysteries regarding what happened that night at The House on the Hill.
