Legends of the Ells 2 The Young Guardians

Immediately after the final departure of the old Ells, the young Guardians are confronted by Xyle, a terrifying new foe with powers that exceed their own. For many years Xyle has prepared plans to seize control of Earth and is ready to execute them.
This raises the task of preserving the Ell legacy to a new level, for Xyle has tremendous resources stretching far beyond Earth itself.
An attempt to discover these brings Yani into deadly danger, far from home.
His feelings for Estella deepen and a new relationship is forged with her father, a former foe. Three new youngsters join the Guardians, one from India, one from China and one from South America.
