“Where The Theory of Everything stood out for me was in how deliberate the voice was in accurately capturing everything Sarah was feeling… As a result, Sarah felt more real and current to me than perhaps any other character I’ve read this year, her story leaping off the page to lodge a place in my head and heart.” ―Blogging for YA

“What I liked best was how Sarah took responsibility for her own recovery. She makes an effort not to be so snarky, she tries to reach out to other people instead of pushing them away, and she really works at being a better person.” ―Confessions of a Bibliovore

“Johnson deftly blends humor and grief in this story… The Theory of Everything keeps readers guessing―and laughing―and crying―to the last page.” ―Cybils

“Johnson delicately unravels the accidental and peculiar death of Jamie while introducing us to a complex and completely hilarious character in Sarah. This snarky and endearing girl ropes you into her heart quickly with her combination of Zoloft-infused wit and wisdom… Johnson successfully illustrates the struggles of a teen dealing with depression while still battling the harsh criticism of her peers. The characters in Johnson’s novel are rich with small town flavor and it is easy to see why she revisited the same setting in her second novel.” ―The Pirate Tree

“It’s a powerful story with a snarky main character that will leave you in stitches and tears.” ―Satisfaction for Insatiable Readers
