So I read the book

1. Clay Mann art is amazing

2. This issue is kinda of set up it does not have a lot there but there is a lot to unpack

spoilers:
3.Body count Blue Jay,Hot spot, Wally West ,Arsenal,Commander Steel and some green merdude. The Blue jay death reveal was a bit unnecessarily brutal imo,It took me second to see it.

4. Harley Quinn and Booster gold are the suspects so far
end of spoilers

I am in curious to where the story goes I am fine with stories have cost if the outcome tells a good story. Most people will focus on deaths but only reason we have these big death focus style events is because comics bring back people. If they left characters dead they could only sparingly use death as gimmick.
