Not a "traditional" book (although there are pirated PDFs and ebook versions of it out there), but the Worm Web Serial is absolutely amazing. Alternate reality where superheroes and villains are common, but told from the perspective of different heroes and villains. Also, it goes really deep into the Universe's logic and science around how powers function and intermingle with each other, their origin, and most importantly, what the experience is like to actually USE the powers by those that have them. It is also quite long--I've heard it is longer than all the Harry Potter books combined. I was sad when it ended though. https://parahumans.wordpress.com/ https://parahumans.wordpress.com/
