Lost Memories

After the last battle, and the defeat of Voldemort, Hermione left in a hurry. No one knew why or where she left. Now five years later she is back, but she's not alone. Can her old life return as it used to, and why did she leave in the first place? Mature content in later chapters. HG/GG and HG/SF. Constructive criticism always appreciated, but don't be rude:3
