I remember reading this one book in 2014. The title had the protagonist's name in it. The story is set in the future where humans are now living on a space ark and have left planet Earth behind. Well technically, they lost the coordinates to Earth so they can't go back anymore.
I can't really remember the storyline but, the protagonist was a boy who was living on the space ark. The boy started having these strange dreams where he would be on Earth as a different person. I can't remember if he could tell if it was Earth or not. In the "dreams" that he had, he had powers? I think he later finds out that he was traveling back in time and living as a totally different person. I think as the story develops, the two different lives that he is living start to intertwine with each other and he finds out stuff about the space ark.
I'm not 100% sure about the information I've provided. The only parts that I'm 100% sure about is the fact that humans are now living on a space ark, they've lost the coordinates to Earth, the boy starts to experience two different lives; one as a boy on the ark and the other as a boy on Earth with powers. An extra piece of information that I'm not sure of is that people on Earth all have powers and the social hierarchy is based on the powers that you have. I think the people that are behind humanity's demise want the history of Earth gone. That includes the fact that humans actually possess powers.
I also remember another character. It was the boy’s professor or teacher in the space ark. I think I remember him being good and he owned a library if I remember correctly or he was the librarian. And just like everyone else, he also didn't know much about the history of Earth and how humans ended up on the space ark but he was very much fascinated about it. This has been eating at me for years now but I can't seem to find the book.
I don't know how accurate this is but if I remember correctly, the cover of the book was of the protagonist's silhouette illuminated in some kind of light. The title of the book goes something along the lines of this, "[protagonist's name] the boy with supernatural powers" or the boy who was chosen. It sounds similar to that but I can't remember.
