Hi Ms. Simone, I am really interested in your run on Secret Six, and I was explaining to my girlfriend about the mixed sexualities on the team and she is also really interested. I find DC doesn't collect comics in trades/hardcover near as well as Marvel. W

Thanks!

They first appear in Villains United, and then the next is Six Degrees of Devastation.  That second one is out of print right now and expensive on ebay but is available on the DC comics app and Comixology, I think.

Then the ongoing series goes, UNHINGED first, DEPTHS second, and then i get confused. :)

You can start with either Villains United or UNHINGED pretty easily, I think!  Good luck and thanks!
