I recently finished the Renegades trilogy by Marissa Meyer. It's an interesting mix of Superheroes + Post-Apocalypse, essentially one supervillain won, and was just barely beaten after he destroyed the world and put it into total hell for 10 years straight, and the team of supers who put him down are now (badly) trying to rebuild from the ashes while the villain's old crew are up to shenanigans. Impressively, the author managed to come up with a reason for the two leads to have secret identities (and hate/love each other's alternate identities) despite the fact that in the post-apoc world, nobody uses them anymore and your superhero name is just a cool tag.
It has two voice readers, a woman for Nightmare's perspective chapters and a man for Sketch's which is always a nice touch on works that have differently gendered viewpoints.
