Over all a fun read. Every one of the stories left me thinking. There were a few that didn't quite hit the spot for me more due to the delivery rather than the story itself. And again, only because those are short stories and the authors don't have much choice than to dive in. It's up to the readers to catch up as quickly as they can.
My favorites in no particular order: Kleptos, Greetings, and Sunnyville, although the last one wasn't totally original.
My least favorite one was Omega. Again the idea was great but I didn't like the switch of POV from third to first to second all in one.
I'd recommend this book for any science fiction lovers.
