Escaping a kidnapping changes you.
Nothing feels safe for Isabel as long as Dr. Rodriguez is still free to move forward with his diabolical plans. Stopping him is the only thing she thinks about.
But Maya is busy thinking about where she'll go to college. (Not near Isabel, that's for sure.) And Aunt Claire is being questioned by the government about her research. (She's the good guy, they should be focused on Dr. Rodriguez!) Then everything goes wrong on a trip to Washington, DC, landing the whole family in hot water. (It's not like they were trying to steal the Declaration of Independence!)
Worried that they'll never be safe again, Isabel has to learn that she can't do it all-defeating evil takes teamwork.
