One day, the parents of 13-year-old Ma Li mysteriously disappeared and so he had to be sent away to a welfare centre for minors. Two months later, he was adopted, then a series of strange events began. First, he discovered his real parents were not just ordinary folk, but were both 'universally' famous scientists: his father in astronomy and his mother in geology. Next, and more bizarrely, that the family who adopted him had arrived from outer space. 

Just prior to the explosion of planet Ma Er, his new, alien parents and their children had miraculously succeeded in escaping the devastation by spacecraft, which eventually reached Earth. 

The alien's hope was that Ma Li's father could help them discover another livable planet. Their other ambition was that they might also try to prevent the nuclear radiation produced on planet Ma Er from affecting the Earth.

Will Ma Li reunite with his real parents? Has the Time Axis, which can save Earth, been found?

Suitable for all ages, this is the first in a series of adventure novels by B Du.
