The 2014 Edgar Awards...
The YA winner is:
Ketchup Clouds, by Annabel Pitcher
From the PW article:
Best Young Adult winner Annabel Pitcher (for Hachette’s Ketchup Clouds) pithily commented that “Young Adult Mystery novels are no more watered down adult mysteries than young adults are watered-down adults.”
Heh. You go, Annabel Pitcher.
