The Legend of the Eight: The Charmed (Book 4)

They did it. They actually did it.

The Eight went back in time and changed history--preventing the Incident and countless deaths in the process. But as they settle into their new lives and begin their senior year for a second (and final) time, they find that there are some things even time travel can't change.

After uncovering a royally dark family secret, the Eight fear that the peace they've sacrificed everything for may now be in jeopardy. They thought changing the past would save the future but are surprised to find that destiny has a way of forcing its own hand.

The Charmed is the fourth book in the Legend of the Eight series.
