Rosi's Doors (Book III): Stuck in the Revolutionary War and reeling from a recent defeat by the British, Time Guardian Rosi Carol must rally a group of fugitives and prepare them for a final desperate battle. Outnumbered and outgunned by a merciless enemy, outsmarted at every turn by and increasingly wicked Kirk, Rosi must marshal all of her wits and her experience to reverse the course of events, save herself and her few remaining friends, and perhaps find a way home.
