Music for Centauri

Shawnis is beautiful, she is brilliant, and she is a senior educator at the Centauri University in Atlantis. She is married, she is sinuous and the perfect age to have children but to her disappointment, she cannot. She is not alone. Natural pregnancies no longer exist on the planet Centauri. The species is being kept in existence through cloning. Shawnis is the unchallenged master at cloning embryos for implanting in females. She is on the board of several clinics that have that purpose only.
But the population is declining at an alarming rate and she is not the only one concerned. A small but elite council has been formed to seek a solution. She is honored to be one of the six. If these, the best minds on Centauri fear their genus will be extinct in three thousand years.
An ancient expedition discovered that the planet Centauri is a twin of a distant planet called earth. Centauri is far more advanced yet the populous of earth is expanding almost too fast. Perhaps an answer lies four light years away.
