Why This Must Be Read: Because it's awesome? Seriously, this one-shot packs an entire world and series of events into less than 8,000 words. It's hilarious, detailed, and thoughtful. The characters are fully fleshed-out and get a plot that keeps you genuinely interested alongside the character interactions. I enjoyed this fic so much that I went back digging for it a second time, and re-read it a third while reccing it just now.
In terms of summary, the authors say this: "Detailing one of Amanda Grayson's first diplomatic assignments, which happens to be on the USS Kelvin."
