Queen Urani has a deadly plan. She has attacked all nine Inner Core Kingdoms with radioactive forces because she wants to rule the planet. The only way to stop her is for all six human children to return to the Core of planet Earth to try to save the Elements. Unfortunately, instead of helping restore power to the Kings and Queens, Emma, Will, Alex, Fira, Kepi and Pax find themselves hypnotised by deadly radiation, tricked, and controlled by Queen Urani. She makes them use their superpowers to attack the Kingdoms and fight against each other in a dangerous battle for their loyalty. Embark on an unforgettable adventure as the six human children face deadly radioactive creatures, as they prove their loyalty and create new friendships in an attempt to save the Elements, each other, and ultimately the entire planet. Loyalty of the Six is the third book in the Chronicles of the Elements; an imaginative children's fantasy series that firmly establishes the Periodic Table as a cast of intriguing characters living in a secret world deep inside the Core of planet Earth.
