Claire and Ben are ordinary schoolchildren. Life is predictable … until one day when everything changes – forever.
Claire finds a mysterious letter asking her to travel to a strange place, alone. Her sister is in danger. She must take Jack the dog and not tell anyone, even Ben. Little does she know that she’s about to become entangled in a world of ancient legends, guided by twelfth-century knights who should, ordinarily, be long dead. Knights who wear trainers, pilot planes, perform martial arts and manipulate time, yet they need her help.
Crawling through tunnels, scaling treacherous mountains, combating evil and betrayal, Claire must face her overwhelming fears and discover her hidden and extraordinary talents. In this new world of spies, lies, premonitions and magic, who can Claire really trust?
As the quest to protect a powerfully dangerous artefact unfolds, Claire learns how much is at stake. If she fails, the devastating consequences are too unbearable to consider.
