The two travel back in time where Margaret is expecting them, despite the exact date that was set in the chronograph to travel back in time being kept secret. The next day, Gwen is called back to the Lodge, where she is surprised to find that she is needed in order to talk to someone in the past, her great-great-grandmother, and the eighth time traveler, Margaret Tilney, in order for her blood to be read in the chronograph, since Gideon had made two attempts to gather Margaret's blood, but both times, she had refused. Gideon and Gwen ward them off, then travel back to their present time. After the meeting, the stagecoach of their carriage is instructed by someone unknown to take the two to a park, where they are promptly attacked by three men. However, Gwen is only left with more questions, and is also suspicious of the Count, who is believed to possess telepathy. Gwen travels to meet the Count, hoping she might find some answers. Gwyneth is scheduled to meet the founder of the lodge, the powerful Count Saint-Germain. Gwyneth is assigned the arrogant and disapproving Gideon de Villiers to watch her. Gwen's blood is fed to the chronograph, the time travel machine that contains secrets of its own, so that she can use it to travel through time smoothly and avoid uncontrolled jumps. Gwen travels through time once more and is finally acknowledged as the final time traveler. The Lodge is skeptical of the circumstances, but decide to watch Gwen to confirm that she has in fact inherited the time travel gene. After her third jump, Gwen's best friend Lesley convinces her to tell her mother, who had apparently counterfeited Gwen's birth documents to protect her from the Guardians. Gwen experiences two more uncontrolled jumps through time, during the third of which she witnesses herself, or a double of hers, kissing a boy she has never met at a ball in the 1700s. Charlotte had been prepared for that duty her whole life, and resents Gwyneth for messing up her life plans.

At first, Gwen is doubtful about her jump in time, since her cousin Charlotte Montrose has always been destined to have inherited the time travel gene that is passed down through the women in their family. Not long after, she unintentionally jumps through time while leaving the house. Gwyneth Shepherd, a 16-year-old student, feels dizzy for the first time during lunch at her school in London. The series follows the story of Gwendolyn Shepherd, a time-traveling girl living in contemporary London. The books have been translated into over twenty-seven languages and sold internationally. The three books are: Ruby Red, Sapphire Blue and Emerald Green.

The Ruby Red Trilogy is a series of three young adult fantasy novels by German writer Kerstin Gier.
