Revolution in Time: Out of Time, Book 10, livre audio

A sudden change in Council leadership puts not only the Crosses but the timeline itself at risk. The new Council no longer wants to protect time, they want to reshape it, starting with the birth of America during the Revolutionary War. However, that isn't the only birth they plan on stopping. For their ultimate plan to work, Charlotte Cross must never be born. Friends old and new join forces to save Elizabeth and Charlotte and keep the world they know from being erased from history.
