This is a complicated, “big” story so I’m just going the hit the high notes. It’s a terrific read and I recommend getting these issues for yourself.
Tony Stark’s ex-girlfriend commits suicide, hoping it will bring attention to dangerous Stark Enterprises research on Gamma Photons.
The fact that the work involves Gamma radiation intrigues Bruce Banner, and he and Stark team up (and also fight, of course) to get to the root of a larger conspiracy within Tony’s organization and also to prevent Tony’s assassination at the hands of his dead ex-GF’s brother.
Again: Good story. The only odd thing here is that we just found out, last issue, that Betty Ross is alive. There’s very little mention of her here, and that was a pretty major revelation for Bruce.
