The Luck of Han'anga

Book One of Five.
An age of peaceful exploration has ended.

The centuries old dream of meeting an intelligent, nonhuman species has finally come true, in the form of the people known as the Leyra'an. But the dream soon becomes something darker when the Leyra'an prove to be more than just humanoid. They are like us to a degree that cannot be explained by chance alone. The search for the answer to this mystery will reveal a universe stranger and more dangerous than the crew of the probeship William Bartram could have imagined, and expose both Humanity and the Leyra'an to the threat of extinction.

For better or worse, that search has begun.
