Power of the Atom (inc. the Secret Origins issue), by Roger Stern and Tom Peyer.

Darkstars

Peter Cannon, Thunderbolt

There won't be a definitive ending and will continue in another limited series.

You haven't lived until you've read the JLI!

And you only really need this bit from Legends

The Darkstars is a great series if you like cosmic DC.

Where to start?

I recently binge read Valor and the LSH from the Magic Wars to the end of the 5 year later run.

Next was JL300/3001

Earth-2/Convergence/Worlds End

I switched gears and...

Superman: Time & Time Again

Sleeping with Black Canary has probably been undone by Flashpoint and changed his orientation I guess...

So Ray Terrill is gay now?

Looks like Captain Atom is back to his old self in REBIRTH. I guess it will be addressed in Greg Weisman's Captain Atom mini coming out next year.

Can we go back before Identity Crisis too?

I was going to go with that or Major Vance Astro.
