Orion's Arm Series

The year is 2072. At the lunar farside radio observatory, an old school radio broadcast is detected, similar to those broadcast on Earth in the 1940s and early 1950s, but in an unknown language, coming from an impossible source, and originating at an equally impossible location—Proxima Centauri. While the nations of Earth debate making First Contact, they learn that the Proximans are facing an extinction-level disaster, forcing a decision: Will Earth send a ship on a multiyear trip to provide aid?

First contact with the seemingly impossible human civilization at Proxima Centauri is not going well. The Earth ships sent to render aid have not been able to reverse the contagion ravaging their population and, worse, many Proximans are now wondering if the humans from Earth are there for other, not so charitable, reasons. Can the extinction-level disaster faced at Proxima be reversed by the combined ingenuity of scientists from both worlds working together?
