I've read only a smattering of Jean. I read the first few Atom stories. I seem to remember that she didn't want to get married until she'd advanced in her career. Of course, I know her marriage ended in an affair and divorce and then she went crazy/evil. But I really don't think that and early depiction as career-oriented are connected. Then again, with Carol Ferris...
I also read some Justice League of America issues where she appeared, culminating in the wedding of Ray and Jean. Liked the lead up showcasing the friendship between Atom and the Hawks.
And then her Eclipso appearance in Blue Beetle.
Is it worth reading any older issues with her or was she never developed as a character or never that interesting? Anyone got any issues to recommend?
