For Alex Donner, a walk in the park with his grandson turns out to be anything but. Retired security specialist and widower Alex Donner is on the run. Ever since a crooked cop tried to kidnap his grandson in broad daylight, Alex isn''t sure who to trust-and who''s behind the corruption.  FBI Special Agent Linda Crawford is tasked with investigating the incident and identifying the hero who thwarted the kidnappers. But Alex has gone completely off the grid, leaving a trail of dead criminals in his wake that points Linda toward something much more sinister than playground politics. On their parallel tracks, Alex and Linda expose a horrifying conspiracy: Children are being quietly abducted around the northwestern United States. As Alex uncovers more and more about this vile network with the help of Alina, a Russian immigrant who has unwittingly been working for the criminal enterprise organizing the kidnappings, Linda gathers the evidence she needs to locate the missing children and bring justice to their families.  A Walk in the Park tells the story of a man who is running for his life and a woman who is hot on his tail. Once their paths cross, their individual lives-and the relations between two of the world''s most powerful forces-will never be the same.
