  1. Ambassador by Tabbycat

    5 hours ago

    Twenty years after first contact with aliens, humanity is finally ready to take it’s first steps out of the solar system. After winning the lottery to determine who should be Earth’s ambassador to the stars, Dustin Smith finds that for the galaxy at large the “building relationships” part of being an ambassador is rather more literal than he’d expected. Now he’s handling interspecies politics, managing a growing harem of alien women and working to get humanity it’s seat at the galactic table. But there’s more in space than just the peace the galactic council has governed over for an eternity, and it’s only a matter of time before Dustin and his crew get pulled into dealing with what lurks in the darkness.
