Chinook Winds by Mary Alford

The tide is turning. Legion’s plot to rule the world is crumbling. But with the nuclear weapons missing, every second becomes critical. And tracking down Martin Collins, the elusive leader of Legion, is Strike Forces’ number one concern because until Collins is in custody, no one is safe.
Secret Service Agent Kinsley Allison has done everything in her power to protect President Victor Douglas from danger. Always putting the job first ahead of her feelings for him and she almost died because of it.
Now, with the world on the brink of chaos, it’s Victor’s turn to protect Kinsley, because losing her to Legion’s desperation, is unthinkable.
