Ye Xuan is the genius girl at First High School, always ranked first in her grade. Her teachers pin their hopes on her competing in the math olympiad, where she has a good chance of winning a recommendation for university admission. Only her best friend, Han Feifei, knows that beneath her seemingly cool and accomplished exterior, Ye Xuan is trapped in a summer she cannot leave behind.
Dandelions drift past the window year after year, and moonlight shines into the room night after night. Two siblings with no blood ties love each other in the most painful way and torment each other in the most silent way. Each wants to bring the other a ray of light, yet both choose to sink into a world beyond its reach.
With the math competition before her and the winds of freedom blowing from afar, can Ye Xuan escape the little alley that has held her captive for five years? Can the carefree young man who appears at the bookstore become the girl’s salvation?
