This is my first experience with a 300 word challenge, and I must say I'm loving the breathing space it affords. Reading through all the stories just now, there's so much extra life in the scene and the characters. It's like a 10 minute prog rock song versus a 3 minute pop radio edit. Shortlist below, with votes in bold.
@Astro Pen - An fascinating idea worthy of a book series!
@Guttersnipe - Just wicked!!
@Bren G - Magnifique!

@Menolly - Charming and delightful.
@Jo Zebedee - Haunting!
@AMB - Equally haunting!!!
@Peter V - A twisted tale of sisterly love and revenge.
@dannymcg - Oh, that is so, so dark! Twlight Zone-style horror.
@Phyrebrat - A lyrical, ambient tale, bordering on hypnotic.
@mosaix - A quirky modern take of vampirism.
