She Who Became the Sun by Shelley Parker-Chan

Zhu was once a worthless girl child whose father couldn't even sell her to feed himself and his son. When she is left an orphan she takes on the name and life of her brother whose destiny was for greatness. She lives at a monastery somehow hiding her female past and then begins to form her own destiny as a warrior monk who knows no fear and whose desire for power is only seconded by a desire for the beautiful Ma. This is CROUCHING TIGER meets MULAN and inspired by the founding Emperor of the Ming Dynasty. Power, determination and a belief in greatness no matter what sex you are born.
Her beautifully choreographed writing style that is as graceful as watching a martial arts exercise.  4 stars
