Hermione celebrates her seventeenth birthday with the help of Ron and Harry. Set during HBP from Hermione's point of view. Implied Ron/Hermione. Excerpt- Since I came to Hogwarts, I have celebrated my birthday alone. First year I had little choice, but beyond that, I did choose. Harry and Ron never notice; I doubt they even know which day it is. But this year, I want it to be different. Why? Because tomorrow is my seventeenth birthday. Tomorrow I come of age.
