Quick. Run, do not walk over to today's entry at Jeff Ford's blog 14theditch where he's posted his story A Night At The Tropics (Part 1) and (Part 2).
Jeff was one of our 2004 Clarion workshop instructors and is a lovely storyteller. I'd not read this story before, but I love it. It combines the perfect pitch family story with the deeply divergent twist which makes it spec fiction.
