Begins at chapter 31 of Pride-of-Time. Hermione does not de-age herself- not everything can be fixed in time, and sometimes the only solution is to move forward with what you have...

The war is over. It has been for three years. Neither side won. Hermione, who is determined to usurp the new government and bring the still-free Death Eaters to justice. It is now her turn to spy, in the unlikeliest of ways.
