Aaron, Becky, Katie, and Josh Wollerton for being
willing subjects of science experiments for fiction.
The Barflies at Baen’s Bar who were willing to
figure out exactly what I said thirteen years ago.
And especially Traci Scroggins, who fought the good fight.
Dedication
To my sister, Kathy Sue Flower
Who is eighteen months older and yet has
always been shorter than me. She wore dresses
that matched mine. She shared long summers of
secret forts and rambling adventures. She slept in
the top bunk of our bed year in and year out.
Because of her, I have an inkling
of what it is to be a twin.
