This heartfelt middle grade novel tackles some big themes including depression, anxiety, and child abuse. 
This story unfolds over a day, but what an exciting day it is as Tacoma meets Denver (who lives pretty much the exact reciprocal of her lifestyle) and finds herself working with Hudgie (who's bullied her for years). The way in which Tacoma and Denver deepen their friendship through sharing memories feels very authentic. The cast of characters in the diner and across towns are colorful and make the story feel full.
While the hints along the way are recognizable to me, an adult, I'd bet a tween would be thrilled with the twists and turns in this adventure. I'd recommend this title to a tween dealing with anxiety or anyone that has had to grow up too fast.
