One Word You Quiet Nerd

Alexander Emery Jensen is your average typical boy. Right?
Well, he's the shy one when he talks to someone new. He never says anything.
Never.
That only changes when he has a new friend.
Kessiah.
She's willing to do anything for him to talk to her, at least one word.
"One word, you quiet nerd!"
These two will go through a lot of adventure, and Kessiah's mission is to make the dang boy talk.
