Level Up by Gene Luen Yang, art by Thien Pham (First Second, 2011).
Here’s what Gene Luen Yang says about Level Up himself:
How do you decide what to do with your life? This question took up much of my head space when I was in my late teens, and it’s also the central question of this book. This is video games vs. med school– a tale inspired by my brother (a medical doctor) and illustrated by my brother-in-cartooning Thien Pham (not a medical doctor).
