Master Of Death 27 not mine but a must read

After a traumatic experience at age 6, Peter Parker hasn't spoken a word. Most blame it on the fact that he witnessed his Uncle die in a horrible fire, this is only partly true. Now, almost 10 years later Peter is given the chance to finally speak, but will he take it? Or is the fear of his Aunt to much for him to take that chance? Either way, Tony Stark can tell something's not quite right about the "kind hearted" May Parker. (Don't get me wrong I love Aunt May! But I always wondered what if we put a little darkness in the character? That's where this AU was born. Peter's life as Spider-Man wasn't easy before and now with a manipulative and abusive guardian, things only get more complicated but he's still determined to listen to his uncles words: "With great power comes great responsibility) [Book 1 of The Broken Nor Series] [Book 2: Octo Callidus Debitum]

What would have happened if Harry had gotten the diary Horcrux instead of Ginny? Harry is confused about many things. Why won't Dumbledore let him stay at Hogwarts for the summer instead of go back to the Dursleys? Why won't Ginny leave him alone, even after he tells her he's gay? Why do Ron and Hermione keep meeting with Dumbledore and not telling him about it? With the help of his new friend, Tom Riddle, Harry answers these questions and more.... (Tomarry) Do not read while eating or drinking or in the middle of the night. This book is very humorous. Apparently.

She first saw him when she was 22 years old, and injured on a mission. He was 10 years old, and visiting an aquarium. Percy Jackson looked into Natasha Romanoff's weary but determined eyes, and decided to help her. And so, he pulled a lever, spilling his class and her enemies into a tank. That was not the last she saw of him. By the time several years pass, the two green-eyed siblings by bond will be known as heroes, albeit of different worlds. Perhaps they don't know everything about each other. But they do know that they will always have each other's backs. He helps her out when her missions don't go the way they planned, which doesn't happen too often. She teaches him how to be a good spy, although that isn't the intention when they start the lessons. And they become very close, just as close as true siblings, in fact. So when Natasha finds herself in a complicated position during the Avengers' Civil War, Percy decides to interfere. And the Avengers are extremely surprised when they meet Natasha's younger brother. Plans are made and set in motion, alliances are completely misconstrued, friendships are tested and broken, and the two siblings find themselves on their own side against the world. However, there's something bigger in the works for the Avengers, and they'll need all the help they can get to face it. Including the two green-eyed siblings in everything but blood. This is largely Marvel canon compliant up until Captain America: Civil War, with Percy's interaction with Natasha being a background to the PJO books. Cover by @cajoling - she's awesome, honestly I'd check out her work as well lol
