"I had a dream about her," Mikey was admitting to Donnie. Leo paused in his work arranging reeds and cattails in the mud. Donnie turned his head to his brother, indicating that he was listening. "She fell to the floor and her shell cracked open, only instead of blood and guts, her spirit came pouring out.
