"Three Kisses: Defenders of the Crystal Casket" by Henry Szabranski appeared in Daily Science Fiction on January 22, 2013. "A prince defends snow white against an attack by seven dwarves."
The best part about re-worked fairy tales is getting a new insight, backstory, or twist. I kept waiting for something original to happen in "Three Kisses," but nothing really materialized. The story did have a good sword fight scene--something not all writers can pull off. 2 out of 7 rocket-dragons.
