After the war, Hermione found her parents in Australia and brought them home. Sometimes, they get "homesick" and visit. After they come back, her mother falls ill. Note: not a happy ending.

Hermione must travel back into time. If she doesn't, the fabric of time will tear. But what must she do there? How is she supposed to know when she doesn't even know how far 'thirteen' turns is? Takes place after DH, probably AU.
