I've been getting some great books recs from here recently. Love reading about first contact with alien races, but I've found many authors go out of their way to create unique and interesting alien races, either this or the story is focussed around humans many years in the future who have colonised other systems. What are you best recs for stories written about the stereotypical little green men style of aliens. Bonus points it's a modern story written in the 2000s or later. My favourite take on this trope is the Asgard from Stargate.
