Simon and Brad face their greatest danger yet--and discover the secret
of the fireball--in the third book of the alternative history Fireball
Trilogy, from critically acclaimed Tripods author John Christopher.
When Simon and Brad were caught in the mysterious fireball--a whirling
ball of light that sucked them into a bizarre alternate world--they knew
a terrifyingly different future was ahead. The world on the other side
was geographically identical to their own, but the societies and history
were completely new...and full of danger.
Discovering a pagoda in California was strange enough, but when Simon
and Brad are captured by slavers headed to China, the future seems even
more hazardous. Especially when they are banished to a remote mountain
retreat with the mysteriously powerful Bei-Kun...and come face-to-face
with the secret of the fireball.
