?Ma Li and his adoptive family went to South America to find his real parents. Since the Amazon river is so long, they planned to start from Peru, the source of the Amazon River.

Thanks to a parrot, they climbed to Machu Picchu, where they came across a terracotta plate. Later, aided by a local herb gatherer, they discovered the identity of Ma Li's parents' kidnappers. Even though the Earth had now been rescued, why would they still not let the hostages free? Was it to do with Eldorado?

This is the second in a series of adventure novels by B Du. Suitable for all ages.
