Level up!
Hambo_
What if you had an XP bar? What if to get strong you had to level up? What if a bit of exercise, hunting and working made you able to carry more weight? Meet Timmy. Timmy is not to normal, he's a nerd. And he has a question, can humans level up?
THIS BOOK IS AWESOME (duh...)
Rated E 10+ for the following: brotherly violence. Scenes of peril.
