I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
This has men-angels being protected because they are weaker than their female counterparts, a trans angel who is stifled by her place and who sets out not only to fight, but to become her true self, and a possibly love story between Angela and Sera (who is the sarcastic about everything trans character.)
I say possibly because it was more clear in Battleworld, but Battleworld is not the Marvel universe. Whether or not they are simply good friends who love each other platonically or actually romantically involved will be seen, I suppose, in Angela: Queen of Hel. Although this series does a lot: it gets the Guardians of the Galaxy involved, explains Sera's past, and sets up Queen of Hel. I wasn't sure why Angela would go there, or take that role, but I see so very clearly now.
It really all has to do with her having no ground to stand on: she's been lied to all her life, and it seems like people, her family, the people she thought were her family, were not telling her the truth. They were either burying it, or believed the lies, and thus repeated them.
All she really has to ground her is Sera. And yes, this smacks of a romantic relationship - especially since the storyline is that they kidnap and try to save, and have to take care of, Angela's baby sister. They become, for s short time, her caretakers: her mothers. There's a similar storyline in the Battleworld storyline about Angela and Sera, although it's more Angela trying to take in Anna Maria, so I'd like to think the romantic aspects hold true as well, but the author has been more definitive about Sera being trans than about their relationship. (And it's merely because they stabilize each other so well, and they work so well together. I guess it just feels like a romantic kind of love to me, but it's never described as such, and it's never spoken of in terms that would make me believe it was a fact.)
In Battleworld, they call each other my love or my sweet; they do not in this. It was actually startling to read Witch Hunter first, and then see them regress into a more ambiguous relationship. Then again, the Guardians fit in perfectly if you've read their series (if not, it might not be clear why she called them), and are just wonderful.
I'm just gonna say it: I'd read a Drax and Sera series.
So overall, so much to love about this. I highly suggest it, and it's on sale here at Comixology. Digital comics, but all one dollar a piece instead of the usual four, or eighteen dollars for the trade. Well worth it on sale. Well worth it full price.
