Defending Elysium

As Brandon Sanderson's #1 bestselling Skyward series celebrates its third volume, Cytonic, travel back in time to the origin of Cytonics in the novella Defending Elysium.
Centuries before Spensa looked skyward from the planet Detritus—back on Old Earth before it was lost—Jason Write faced a crucial question: was humanity ready to join galactic society?
When faster-than-light communications were discovered by a small telephone company in 2071, alien species such as the Tenasi and Varvax overheard them and came to visit Earth. Because the Phone Company controls all communications with the aliens, their operatives like Jason operate above the law.
Now, on the space platform Evensong, one of the Phone Company's scientists has gone missing before surfacing in a hospital with amnesia, and Jason is sent to investigate. Right as he arrives, the body of a murdered Varvax ambassador is discovered, sure to cause a galactic incident. Coln Abrams of the United Intelligence Bureau seizes the opportunity to investigate Jason as he deals with the crisis. This could be the UIB's chance to discover the Phone Company's secrets—how does FTL communication work, and what is Jason hiding?
