Billion-Dollar Ransom

It would take a perfect plan to collect a billion-dollar ransom.
So here's the plan.
Five innocent people. In different locations. All kidnapped at the same moment in time.
Two children taken from a private school bus. A film producer and a movie star grabbed at a hideaway resort. A beautiful wife whisked off the streets of Beverly Hills.
A billionaire wants his family back.
The cash, gold, jewels, crypto are all ready.
There's only one problem: Stubborn and brilliant FBI agent Nicky Gordon also has a plan. And she doesn't want to pay the kidnappers. Not a dime.
