Book Review: My Best Friend’s Exorcism

What if The Exorcist was funny?

I’m not going to lie, I bought this book because of the cover. It’s like an ’80’s VHS tape sitting front row on my bookshelf, not only reminiscent of days gone by but aesthetics that are getting a second wind (think Stranger Things, Glow, American Horror Story: 1984). I couldn’t resist. I picked it up, rolled home on my thrift-store roller skates and read it in two days flat.

Plus, the reviews were hilarious. Scary Sixteen Candles, Mean Girls but with demons, if The Exorcist was written by Tina Fey. And the reviews of author Grady Hendrix are similarly impressive. This is the first book I’ve read of his and it made me want to read everything he’s ever written. As soon as I finished it, I skated my way back over to Barnes & Noble with Pat Benatar blaring on my Walkman and bought two more of his books.

Hendrix shot to fame with his debut novel Horrorstör in 2014. The book is stylized as an Ikea catalogue and is honestly one of the coolest books I’ve ever seen. Hendrix has been publishing various works since 2012 and shortly after Horrorstör came an onslaught of instant best-sellers; My Best Friend’s Exorcism in 2016, The Southern Book Club’s Guide to Slaying Vampires in 2020, and The Final Girl Support Group in 2021, just to name a few. He won a Bram Stoker award in 2018 for his non-fiction study Paperbacks from Hell (2017) and just about every book he’s ever written has been or is currently being adapted for TV and film (including this one!). Anyway anyway anyway. Enough about him. Let’s get to the good stuff.

My Best Friend’s Exorcism follows the unlikely friendship of ’80’s teens Abby and Gretchen, two girls from wildly different backgrounds just trying to survive bullies, boyfriends, and demonic possession. Ah, high school. Their relationship begins in elementary school, bonding over roller skating and E. T. the Extra-Terrestrial“If you want to have a normal life, you have to see E.T. People are going to think you’re weird if you don’t.“… and experimenting with LSD… “Because I want to know if Dark Side of the Moon is actually profound.” It’s in the aftermath of this experimentation when Gretchen begins to act differently. Nightmares lead to insomnia lead to paranoia and terrifying outbursts of violence toward her friends and… well, you can read the title of the book.

The story unfolds to a synth-heavy 1980’s soundtrack and neon backdrop, a stark contrast to the horrific events that take place, all tied together with a pink sequined scrunchie. Trigger warning for potential readers: this book contains explicit and detailed discussion of sexual assault, suicide attempts, and eating disorders.

It’s clear the story revolves around found families and young friendships and the sometimes surprising strength of those bonds, even in the hardest and darkest of times (you know, like when your BFF is possessed by a demon and ruthlessly tormenting you and your other friends). Beneath the ’80’s song lyrics and lingo and hairspray is a heartwarming tale of sisterhood. In the book’s most touching moments, I found myself thinking about my best friend and our bond and what it might withstand. Without hesitation, I would say it could withstand anything. This book, however, made me wonder. Could our friendship defeat the Devil himself?

There are several laugh-out-loud moments peppered throughout the building terror – drunken banter between a group of high school girls, for example. But then the switch flips, and in the course of one summer night, everything changes. Drunken nights between a group of friends unravel into a hellish nightmare. Hendrix describes Gretchen’s descent into madness in horrifying detail, from her cracking skin to her matted hair to her rotting, sour smell. It’s a haunting image, and one you’re not going to easily forget.

This book was rightfully sold and marketed as adult horror (and that’s where I stumbled across it at my local Barnes & Noble). Profanity and mature themes abound. Haunting and at times straight up gory images unfold rapidly as the plot thickens and builds to the epic showdown at the finale. The fate of one of Gretchen’s friends (left unnamed here due to spoilers) left me feeling particularly squeamish. Though I might not recommend it to those with a weak stomach, it’s not unbearable.

Despite the overwhelming pop-culture references and religious trauma and demonic possession, the undercurrent of the story is clear: the power of friendship. The power of love and sisterhood binds this whole terrifying mess together like a neon trapper keeper and leaves even the most terrifying bits palatable and easier to digest. Somehow, Hendrix wove a touching and honest portrayal of friendship into this tale of demonic possession and did a damn good job of doing it. It’s fascinating how the two main themes are so drastically different and yet weave perfectly together in this Heathers x The Exorcist mashup. Totally tubular.

Abby and Gretchen made a pact as kids to still be friends by the return of Halley’s Comet in 75 years. Despite the gore and violence that took place by Gretchen’s hand (or was it the Devil?), I really wanted them to get to see that damn comet. Right up until the very last page. Do you think they make it? Only one way to find out…

My Best Friend’s Exorcism really ticked all my boxes. Found family, ’80’s music, religious trauma, and girl vs the Devil. It also gets bonus points for making me cry. Twice.

5 stars overall. 3/5 stars on the scare scale.

Reader beware, you’re in for a scare! Or not. Trick-or-treat, after all.
