In Book II of Rosi's Doors, Rosi Carol has managed to settle into her Uncle Richard's New England castle, despite having her family's so-called gift thrust upon her. Rosi has the ability to step through time, which means she also bears the responsibility to be a Time Guardian. Or rather Apprentice Guardian, as her Uncle Richard keeps pointing out. When she and her friends are dragged through a time portal into the past, Rosi must figure out where they are, when they are, and how to restore the timeline.
