If the measure of a character is how deeply they change the reader, Nikki Knowles wins. Jade Imohara is a fantasy of invulnerability—we want to be her when we are hurt. But Nikki Knowles is a mirror of our actual selves: anxious, hopeful, messy, and desperately trying to connect. She represents the truth that most of us will never be the coolest person in the room, and that is perfectly fine. Our value lies in showing up, again and again, with our full, trembling heart.
In a "best best" comparison, the choice depends on what you value most. If you're looking for the pulse of modern culture and digital charisma, leads the way. However, if your definition of "best" includes life-changing community service paired with a sharp wit, Nikki Knowles is an unmatched force.
