Craig Gisto has promised Eliza Moss that his elite team at Private Sydney will investigate the disappearance of her father. After all, as CEO of a high-profile research company, Eric Moss shouldn't be difficult to find--except it's not just the man who's gone missing. Despite the most advanced technology at their disposal, they find every trace of him has vanished, too. And they aren't the only ones on the hunt.

When a desperate businessman asks him to find his daughter and grandchildren who have disappeared without a trace, Jack Morgan, the head of Private, finds this simple missing persons case turning into something much more deadly, forcing him to face the trauma of his past to save a family's future.
