Found this at Walmart yesterday!
The original story is "The Conversion" and is remarkably small (12 pages). In it, Diana and Steve save a group of women who were traveling to attend a humanitarian aid conference in Bialya from terrorists. Suddenly, Ares appears to her and talks about the power he has over all mortals and even Diana herself. As she is about to be corrupted by Ares, a terrorist goes to shoot her until the ceiling begins to collapse. Diana, rushing to her senses, saves the man, and he is shocked that she would save his life. She tells Steve that she'll be there to end his influence, even if she has to convert his followers one at a time (she says this while embracing the man in tears).
So, yeah. Loved it. Seeley needs to write the main Wonder Woman title. He gets the character and all she stands for.
As for the question: When does this take place? It's very possible it takes place in Rebirth, as Wonder Woman's in her full costume and Steve is still young and attractive. But the biggest problem is Ares. Diana says he's trapped in Tartarus and was projecting an illusion of himself. That's entirely possible, but as we know Ares is fully content to stay in his prison in Rebirth. Unless Grail is having her own corrupting influence on him... I guess that could work.
Also, Diana mentions that she's not a god. Just an Amazon from Themyscira. It's possible she considers herself to be an Amazon like her sisters rather than a god, but it clashes with the demigod origin and her acceptance of Zeus in Robinson's run. Either way, this one I'm okay with Seeley ignoring.
The only disappointing part of the short issue? The art. I'm really not a fan of the style used here.
And for those interested: the other issues presented here are Justice League #1, Flash #1, and Aquaman #1, all from the New 52 era.
