A Leaf on the Wind of All Hallows by Diana Gabaldon

This short story can be found in George R.R. Martin's Songs of Love and Death, an anthology of short stories by modern masters.
I LOVED this story. It is the story of Jerry and Dolly MacKenzie, Roger's parents who are briefly mentioned in the Outlander series. This story is apparently referenced in An Echo in the Bone. I have not yet listened to this Outlander book because I am waiting for Susan to finish A Breath of Snow and Ashes...but I'm not sure how much longer I can wait after reading this short story!

Lord John and the Hand of Death by Diana Gabaldon

I went to Indiana last week to visit my brother and had surgery on Thursday after my return. With these breaks in my schedule, I knew I wanted to find something to read that would not need a big commitment. So, I decided to read some of DG's short (i.e. not 1500 pages) works of fiction. This books is one short story and two novellas regarding Lord John Grey, a minor, though influential, character in DG's Outlander series.
I enjoyed these stories, though not as much as the Outlander books. Interestingly, all tree of these read like mysteries, my favorite genre. I would recommend reading these once you have exhausted the Outlander books.
