The novel “The Moon Children” by Jack Williamson was published for the first time in 1971, serialized in the magazine “Galaxy”.

In the years after the first Moon landing, space missions are pushed farther and farther away carrying astronauts to other planets in the solar system. These trips find possible alien life forms but some discoveries are strange and have unpredictable consequences. The astronauts on a mission to the Moon see different things and when they return to Earth their testimonies are contradictory. As if that weren’t enough, their wives give birth to children with abnormal characteristics.
