Jo, Caylin, and Theresa were just average girls until they were chosen by a top secret organization to be trained as a trio of virtually unspottable spies assigned to protect the world from any and all dangers and disasters. Training might've been a cinch, but the girls have no idea what's in store when they have real missions in the field. Infiltrating the American embassy in London to prevent an assassination, tracking down a missing ballerina in Eastern Europe, taking down a techno-terrorist group in Seattle -- the adventures never stop. When everything is at stake, Jo, Caylin, and Theresa must be sure to make the right choices. But even with all their gadgets, training, and teamwork, some obstacles are just too much to handle. And sometimes love can be the biggest obstacle of all.
