Eighteen-year old Keira Wilde has finished school and is determined to make her own plans for her future, thank you very much. She wants to be a photographer; not go to Oxford, like her parents want, or be a hero, like her aunt wants. But Keira's plans go flying out of the window when she is attacked on the streets of London and she is forced to use her powers in self-defense.

Unfortunately, her actions attract the attention of a predator intent on using her...or destroying her. Preferring to be neither used nor destroyed, Keira takes charge of her destiny and enters the hidden world of the Guardians of the Akasha.

Fighting side by side with the battle-scarred Marco Santana, they race from London to Argentina and a castle in the forests of the Czech Republic to find the source of all knowledge and prevent the fabric of time from unraveling.
