Summary: Brooke is just like any teenage girl. She has friends, she has a boyfriend, she goes to school (well, kind of). The only difference that separates her and nineteen others from the rest of the world's 16 year old's is they're in the CIA. They've recieved extensive training that even excels above many adult agents. But that's all they have had: training. So when they're called out into the real world, Brooke knows something is up. They soon learn that Adult agents have been disappearing rapidly for the past few years, and nobody knows why. After completing several minor missions, Brooke stumbles across information that is much more serious than it first appears and may be the key to unlock the disappearances. But when she tries to warn the agency, very few believe her, and when a problem erupts, people start to point fingers at Brooke. Before she knows it, Brooke finds herself forced into the most shocking of alliances, and she embarks on an incredibly dangerous mission to clear her name. Facing love, friendship, and betrayal, Brooke finds herself on an emotional roller coaster, and she soon realizes that before she can save the world, she must first decide where her loyalties lie.
