Charlie Thorne and the Last Equation by Stuart Gibbs

Hold on to your seat, it's going to get bumpy!!  Charlie (AKA Charlotte) Thorne is a mathematical genius.  She is 12 years old and already in college. The CIA kidnaps her and puts her into service in exchange for a crime she committed - stealing money from a company.  She discovers that they are hunting for Pandora, a equation developed by Einstein and hidden away so it doesn't fall into the wrong hands, but who are the wrong hands?  CIA, Mossad, MI6?  Charlie doesn't know who she can trust.  

Plot has lots of twists and turns and will keep you guessing to the end.  Gibbs has left it open to a sequel, I hope he produces one. :)
