"Besieged" by Diana Gabaldon was a bit too short for me to get fully invested in the story.
I would have enjoyed it much better if we could have gone a bit more in depth into both subplots--the siege of Havana *and* the slave revolt.
Still, the writing style was impeccable as always, and the plot twist at the end absolutely gut-wrenching.
My favourite quote from this short story (which might very possibly be my favourite quote in the whole Outlander universe) is:

Spoiler

"The duty of a survivor. Not everyone lives to be old, but if you do, I think you owe it to those who didn't. To tell the stories of those who shared your journey... for as long as they could."

This sentence is beautiful and delicate and, in my opinion, the best description of literature I've ever encountered.
