An alternate point of view to 0nceuponawriter's 'Lie, Spy, Don't Die' :

Zara York does not live a glamorous life. After her father dies under "mysterious circumstances", she is left under the care of her Stepmother along with her step brother and sister. Hoping there is more to life than abusive siblings and a rampaging mother, she runs away, changing her life a great deal more than she could ever have imagined. It's not very often that you get chosen to train at the world's most top secret, elite spy academy.
