Circumstances change. Mission statements change. And one little boy's life will change and he will change the lives of people half a world away.

Harmony Potter is actually Harmony Rabb, the only daughter of Lieutenant Harmon Rabb Jr. of the Judge Advocate General Corps and a wizard. When Harmony leaves for Hogwarts, Harm is paranoied about the trouble she's likely to attract, being a JAG cadet, an American and his daughter. They say like father like son? More like father, like daughter in the Rabb's case.

While on vacation, Mac rediscovers powers she once had. However, there's always a catch... JAG/Harry Potter crossover. AJ/Mac.
