Title: Secrets (Undercover Girl, #1)
Description: Jesse Sharpe is no ordinary kid.  She's an orphan, a genius, and a secret agent.  Jesse has been assigned by C2--the mysterious organization that raised her and taught her to be a spy--to protect another girl from a kidnap attempt.  Jesse will have to trail suspects, plant listening devices, crack codes, and kick occasional bad guy butt.  What Jesse doesn't know is whether she can trust C2 and the information she has been given--or someone within the organization is trying to blow her cover.
