The Spy Girls is a trio of agents for the Tower.
Each of the three young women, newly graduated from high school, was thrilled with an invitation to travel to Washington, D.C. and be interviewed for a possible placement with fun-sounding program. Sort of like the Peace Corps, they were thinking. They were surprised to learn that the organization calling them was one called the Tower and it was an intelligence organization. And it wanted them as agents. That was a shocker.
So was learning that each of the three had been followed and monitored and analyzed since the 7th grade because each shows such remarkable potential. And now it was time to bring them into the fold, train them, and let them out to handle missions all over the world. While all that was indeed shocking, so was the fact that each of them said yes.
The next sixteen weeks were spent in "Bond-style training" learning all sorts of things they would need to be the kind of spies that the Tower had long predicted they would be. And during the four month period, three women who had never met also learned how to operate as a team. Jo Carreras, Caylin Pike, and Theresa Hearth were their names.
Carreras was the daughter of a Cuban lawyer who escaped to Florida as a teenager and worked his way up the legal ladder to eventually become a judge. She had been on hand when a drive-by shooting had gunned him down leaving her an orphan at 14. The rest of her upbringing was done with an Aunt. That murder, though, had changed a straight-laced "good-little-girl" named Josefina into Jo, "the fun-loving, boy-crazy, connoisseur of fast food, faster fashion, and the fastest cars on earth".
Pike had become a world-class skateboarder who could have made a name for herself there if the Tower had not called. She got that good through constant practice, sometimes ignoring other lessons. Getting that much time to train came about because she also learned many different ways to break curfew, get out and get back in without being caught.
Hearth was the most timid of the three, worried that she would not have what it took out in the real world to do her job. She saw herself as a "computer fiend" who was "more used to working on the sidelines than being in the eye of the storm".
A party-animal, an athlete, and a computer whiz now make up the team given the codename Spy Girls.
