Looking for a complete, spoiler-rich summary of the Ruby Red Trilogy Summary by Kerstin Gier? You’re in the right place. This guide gives you a clear breakdown of all three books—Ruby Red, Sapphire Blue, and Emerald Green.
The trilogy follows Gwyneth Shepherd, a London teenager who discovers she’s inherited the rare ability to travel through time.

The Premise: Time Travel Within the Bloodline
The Ruby Red Trilogy Summary is grounded in a unique concept: only twelve individuals throughout history inherit a time-travel gene, passed down through two intertwined families: the Montroses and the de Villiers. The secret society known as the Guardians monitors and controls time travel via a device called the Chronograph.
Two final gene carriers—one male and one female—are prophesied to complete the “Circle of Twelve,” triggering a powerful but mysterious outcome. Gwyneth was never supposed to be the female traveler. That role was meant for her cousin Charlotte. But fate intervenes.
