Luna's control agent, Jennifer Kajiwara, is given an ultimatum by her superiors in the Agency. If Luna fails in her newest mission, Project Luna will be terminated-permanently. As Luna delves deeper into the shadowy organization known as Knightfall, what she learns may not only derail her mission, but it could tear apart her makeshift family forever. Super-spy action and high school romance continue in this newest installment of Amazing Agent Luna. This volume directly ties in with events that occurred in the two-volume Amazing Agent Jennifer prequel, but can be read independently.
