If you haven't heard of a book with a name that long, you're probably wondering if it's a cookbook or a history text. It’s neither. Honestly, The Guernsey Literary and Potato Peel Pie Society is one of those rare cases where a book became a sleeper hit through pure word-of-mouth before it ever hit the big screen. It's a story told through letters. Epistolary, if you want to be fancy.
Mary Ann Shaffer and Annie Barrows wrote something special here. Shaffer actually died before she could see the book's massive success, leaving her niece, Barrows, to finish the heavy lifting on the manuscript. It’s a bittersweet origin story for a book that is, at its heart, about finding light in the darkest corners of human history. Specifically, the German occupation of the Channel Islands during World War II.
Most people know about the Blitz. They know about D-Day. But the occupation of Guernsey? That’s a niche bit of history that many folks—even history buffs—tend to gloss over.
The Weird Truth Behind that Ridiculous Name
Let’s get the elephant out of the room. The title sounds like a joke. It’s not. In the book, the "Society" is born out of a desperate, split-second lie told to German soldiers.
Imagine you’re walking home in the dark. You’ve just broken curfew. You’ve also just eaten a pig that you weren't supposed to have because the Germans had requisitioned all the livestock. You're full of roast pork and a bit of gin, and suddenly, you’re staring down a patrol. Elizabeth McKenna, the heartbeat of the novel, invents the "Guernsey Literary and Potato Peel Pie Society" on the spot to explain why a group of locals is out late. They were at a "book club," she claims.
The lie sticks. To make it believable, they actually have to start the club.
And the pie? It’s a real thing. Sort of. During the occupation, food was so scarce that residents had to get creative. A potato peel pie is exactly what it sounds like: mash, strained peels, and no butter, flour, or sugar. It was "sustenance" in the bleakest sense. Shaffer used this detail to ground the fiction in the grim reality of 1940s Guernsey.
Why the Epistolary Style Actually Works
A lot of readers shy away from books written entirely in letters. It feels clunky. Or it feels like you're missing the action. But here’s the thing: in The Guernsey Literary and Potato Peel Pie Society, the letters are the only way the story could feel this intimate.

We start with Juliet Ashton. She’s a writer in post-war London, 1946. She’s tired. She’s famous for a series of humorous columns she wrote during the war under a pen name, but she wants to write something "real." Then, she gets a letter from Dawsey Adams. He lives on Guernsey. He found her name and address inside a second-hand copy of Essays of Elia by Charles Lamb.
He just wanted to know where to find more books by Lamb.
That one letter sparks a chain reaction. Juliet starts writing to the whole society. We meet Eben Ramsey, the fisherman; Isola Pribby, who makes herbal "potions" and keeps a pet goat; and the tragic, brave Elizabeth McKenna. Through these letters, Shaffer captures different voices—crusty, elegant, terrified, and hopeful.
It works because it feels like you're eavesdropping. You aren't just reading a plot; you're discovering secrets. You're seeing the scars the war left on people who are trying to pretend everything is back to normal when it clearly isn't.
The History Google Searches Don't Always Tell You
Guernsey wasn't just "occupied." It was transformed. The Germans wanted to turn the Channel Islands into an impregnable fortress. They brought in thousands of "OT" workers—Organisation Todt slave laborers—mostly from Eastern Europe and Russia.
The book touches on this, but the reality was even more harrowing.
- The Evacuation: Before the Germans arrived, nearly half the population fled to mainland England, including thousands of children. Families were split for five years.
- The Hunger: By 1944, the islands were cut off from all supplies. Both the locals and the German soldiers were literally starving to death. The Red Cross ship, the SS Vega, finally brought food parcels that saved the population.
- The Fortifications: You can still visit the "Hospitals in the Rock" and the massive concrete bunkers today. They are eerie reminders of a regime that expected to stay forever.
When Juliet travels to the island in the book, she’s stepping into a landscape that is physically and emotionally battered. The "Literary Society" wasn't just a hobby; it was a way to keep their brains from rotting while their bodies were failing. It was a form of psychological resistance.

The Lily James Movie vs. The Book
In 2018, Mike Newell directed the film adaptation starring Lily James as Juliet and Michiel Huisman as Dawsey. If you’ve seen the movie, you might think you know the story. You mostly do, but the book hits differently.
The movie does a great job with the visuals. The sweeping cliffs of the Channel Islands (actually filmed in Devon and Cornwall, mostly) are stunning. But the film has to simplify the mystery of what happened to Elizabeth McKenna. In the book, the search for the truth about Elizabeth is more of a slow burn. It’s a detective story wrapped in a romance.
Also, the book's Isola Pribby is way weirder and more wonderful than her movie counterpart. If you like eccentric characters, the prose gives them room to breathe that a two-hour runtime just can't afford.
What People Get Wrong About the Ending
People often categorize this as a "light" historical romance. That's a mistake. While there is a romance—and it’s a sweet, slow-building one—the ending is actually quite heavy.
The story of Elizabeth and the German doctor, Christian Hellman, isn't a "forbidden love" trope used for cheap drama. It’s a look at how war forces good people into impossible positions. The book doesn't give everyone a happy ending. It acknowledges that some things, once broken, don't get fixed.
Juliet finds a family on Guernsey, but she also finds a community that is deeply traumatized. The "Potato Peel Pie" is a symbol of that: it's something bitter and hard that you swallow because you have to.
Lessons From the Society
So, why are people still reading this book in 2026? Why is it a staple of book clubs worldwide?

It’s because of the core message: books are a lifeline. In the story, literature gave these people a reason to gather when gathering was dangerous. It gave them words for their pain. Whether it’s Seneca, Catullus, or Charles Lamb, the characters find pieces of themselves in the pages.
If you’re looking to dive deeper into the world of the Society, there are a few things you should actually do.
Check out the real Guernsey
If you ever get the chance, go to the Channel Islands. Visit the German Underground Hospital and the German Occupation Museum. It’s one thing to read about the "fortress island" and another to stand inside a cold, damp tunnel carved out by slave labor.
Read the "Inspirations"
Juliet and Dawsey bond over Charles Lamb. If you want to see what the fuss is about, pick up Essays of Elia. It’s dense, 19th-century prose, but you’ll start to see why a lonely man on a starving island would find comfort in it.
Dig into the Authors' Background
Read about Mary Ann Shaffer’s trip to Guernsey. She got stranded there during a fog in the 1970s and spent the time reading books about the occupation in the airport pharmacy. That’s where the seed for the whole novel was planted. It’s a reminder that sometimes, being stuck somewhere you didn't plan to be is exactly what you need.
Look for the "Unseen" Characters
In your next re-read or watch, pay attention to the characters who aren't there. The letters often mention neighbors who turned a blind eye or those who collaborated with the "Jerrys." The book is surprisingly honest about the fact that not everyone was a hero. Some people were just trying to survive, and survival often looks messy and unheroic.
The Guernsey Literary and Potato Peel Pie Society isn't just a quirky title. It’s a testament to the fact that even when the world is falling apart, we still need stories. We still need to talk to each other. And sometimes, we still need a really bad piece of pie to remind us that we're alive.
To truly appreciate the depth of this story, start by looking into the actual Red Cross relief missions to the Channel Islands in 1944. It provides a sobering context to the "potato peel" era that makes the fictional Society's resilience feel even more miraculous. After that, pick up a copy of the book—even if you've seen the movie—to experience the character voices that only the epistolary format can truly capture.
