I stumbled upon Penpal after seeing a string of comments under a Pinterest post. The buzz around it was impossible to ignore—dozens of readers claimed the book was so terrifying they couldn’t sleep for days. Being someone drawn to all things paranormal, I thought I had finally found my next spine-chilling read. Excited and too impatient to wait, I tracked down a PDF version and dove right in, hoping for a story that would keep me awake at night.
Written by Dathan Auerbach, Penpal first emerged from a series of creepypasta posts, which later evolved into a full-length novel. The story unfolds as a series of interconnected recollections narrated by an adult protagonist piecing together eerie incidents from his childhood. The premise itself is brilliant: a seemingly innocent classroom pen-pal project spirals into something far more sinister and disturbing. The plot’s foundation is hauntingly simple, which is where it finds its strength.
The book begins innocently enough, with the protagonist recounting his memories of sending balloons into the air with letters attached as part of a school activity. When one balloon lands far away, an unknown individual finds his note and starts writing back—leading to a chilling realization years later that he has been followed, watched, and possibly hunted for most of his life. It’s this sense of helplessness and inevitability that gives Penpal its unsettling edge.
Auerbach’s narration shines through in the way he captures the feeling of childhood innocence and naivety. At first, the narrator’s memories are fragmented and hazy, mirroring the way children process reality. The pacing is slow and deliberate, almost teasing readers into thinking they are safe, only for the narrative to drop hints of something far more sinister lurking in the background.
One of the most chilling sections is from the story “Footsteps.” As a child, the narrator would wake up in the woods without any memory of how he got there. “Sometimes I’d wake up to the sound of someone calling my name, but when I opened my eyes, I was surrounded by trees and silence.” This recurring incident is delivered with such a quiet, creeping dread that it sets the tone for the rest of the book. It’s unsettling because it taps into primal fears—being lost, vulnerable, and stalked by someone unknown.
Similarly, the story “Balloons” reveals how a series of photographs sent to the protagonist reveals the terrifying truth: someone had been following him for years. The photos capture not just him but the subtle presence of someone nearby—hiding in the shadows, partially obscured, or just out of focus. “There I was, sitting cross-legged on the grass, staring at the camera with a faint smile. Behind me, half-hidden in the brush, was a man.” This particular scene stands out as one of the most memorable and disturbing in the book. The realization that someone was documenting his life, hiding just out of sight, hits hard and sends chills down the spine.
However, while these individual moments work well, the overall plot remains predictable. As I made my way through the chapters, I couldn’t shake the feeling that I already knew where the story was headed. The mysterious figure watching him, the increasingly eerie incidents—it all pointed to a conclusion that, while disturbing, lacked the unpredictability I was craving.
The book’s tone also leans heavily on nostalgia, which sometimes distracts from the horror elements. The protagonist’s detailed descriptions of childhood moments—like playing outside with friends or school projects—feel genuine and relatable but often slow down the tension. While Auerbach’s writing is immersive, it occasionally loses its grip on the reader’s fear.
For a book often described as “terrifying,” I personally didn’t find myself scared. Yes, the creepy undertones and unsettling scenarios were effective, but they never pushed me to the edge. I finished the book in one night, pulled along by the engaging prose and my curiosity about how it would all end. However, when I finally closed the last page, I couldn’t help but feel disappointed. The resolution, while fitting, lacked the emotional or psychological impact I had anticipated.
That said, Penpal does succeed in creating an atmosphere of dread, and for readers who are new to the horror genre, it might deliver the chills they’re looking for. The story taps into the deeply unsettling idea of being watched and hunted without your knowledge—something that resonates on a primal level.
All in all, Penpal is a solid one-time read. While it didn’t scare me the way others claimed it would, I still found it engaging enough to finish in a single sitting. It’s an unsettling and well-written story, but one that ultimately feels predictable and doesn’t quite deliver on its chilling reputation.
If you’re curious about the hype, I’d recommend giving it a try—but maybe don’t expect it to haunt your dreams.
