I’m looking for a book I think I read maybe in 2018. I don’t remember much, but I remember reading it in middle school, so I believe it would be in the more advanced part of a children's section of the library.
It goes like this: this boy ran away after discovering he had super human abilities, and was being controlled like a machine. The whole FBI/organization was after him, because he was like a weapon for the military or something. But I think he ended up being taken by said organization, and was in training by the military to be the country’s weapon.
Along the way, he finds out his parents created him for the sole purpose of experimenting on him. He’s like half-cyborg, I guess, because he had this machine inside him that controlled him. One ally he met was a tea house owner who let him stay in the upstairs of the store, it was like a old apartment.
If it helps, the cover was black, except for the outline of a door opening, which was colored in red, and the boy was running through it (the door). I think it was also part of a series of books. Anything helps, so if you know what book I’m talking about, please tell me! Thanks so much! Edit: I believe it was published early 2010s. The book cover was all black, there was a outline of an open door, it was colored red and the main character is running through it. This book may be hard to find, I remember searching about it when I first read it and the author wasn’t super well known. He didn’t write many books and I believe this book was one of his last. It’s surprising how much I know but just can’t remember it’s name
