World Hopper: Traveling the Cosmos

World-Hoppers; existences Chosen by the World Tree. Beings that are capable of Traversing the Cosmos. Will Oliver Survive the endless Cosmos, and climb to the top with the greats, or will he fall to the bottom? (This is my first novel so it will probably suck. A lot. I will be using it as a form of practice.) Thank you to all readers!
