I like that the falling snow globe covers everyone behind it except Sally -- and Blake. Ooo, foreshadowing on the cover!
Butterfly and snow is a great image. I didn't know why Ozy had to open the dome, he could have just dumped the bodies in the intrinsic field subtractor.
So the minute hand actually moves from the first cover to the last, cool. Shouldn't it be 12:35 for Ozy? XD
