The Alchemist’s Codex Is Out Now: Eden Black Hunts Fulcanelli Through Paris

The Alchemist’s Codex is out now. Eden Black’s eighth archaeological thriller takes her from a body hidden inside Notre-Dame de Paris to the catacombs beneath the city, a secluded French château and the last stronghold of the Cathars, all in pursuit of the legendary alchemist Fulcanelli and the secret of eternal life.

What is The Alchemist’s Codex about?

What if the secret of eternal life is real, and someone has already used it?

When Eden Black finds a dead man inside Notre-Dame de Paris, one detail makes no sense. The body is hundreds of years old.

All the evidence points to something impossible. The dead man is Fulcanelli, the legendary alchemist who claimed he had found the secret of eternal life, then disappeared.

But with the discovery comes danger. A pharmaceutical billionaire has already spent millions searching for Fulcanelli and his lost codex. The book is a threat to his empire, and a secret he’ll kill to control.

From the cathedrals and catacombs of Paris to a secluded château and the last stronghold of the Cathars, Eden must find the codex before the one man who would destroy it forever.

The Alchemist’s Codex is a race-against-time archaeological thriller for fans of Dan Brown, Scott Mariani, Steve Berry and James Rollins. It’s book eight in the Eden Black archaeological thriller series, but like every Eden Black adventure, it works as a standalone read too.

Launch day: when a book stops being mine and starts being ours

I always say I love launch day because it’s the day a book stops being mine and starts being ours, and I truly believe it. I write the books, create the characters and give them challenges, hopes and dreams, but they only live and breathe when you read the adventure.

With this book, that means more than ever. Just a few weeks ago, the story came to life when we went on a real Eden Black–esque adventure with a group of people who met through reading my books. We didn’t fight anyone, and there weren’t any car chases, but we explored some fantastic legendary places and made some amazing memories together. You can read all about it in The Real Treasure of the Templars: Our First Adventure Society Expedition.

People always talk about real life inspiring fiction, but here fiction inspired real life, real memories and real friendships. That’s powerful stuff, right?

Launch day!

So when you pick up your copy of The Alchemist’s Codex and dive headlong into the twisting path of Eden’s next adventure, you’re not alone on that trail. Thousands of other readers are diving into the same adventure at the same time, following in Eden’s footsteps and, in a way, experiencing it with each other.

The real France behind the story

As with all my books, I travelled to the places Eden visits. Mrs R and I took a campervan around France to research the locations, from the streets of Paris to the remote Cathar country of the south. If you want to see the real places behind the book, explore my France travel and location guide.

Notre-Dame is where the story starts. Fulcanelli’s famous book Le Mystère des Cathédrales, published in 1926, claimed that the carvings of Gothic cathedrals like Notre-Dame hide the secrets of alchemy in plain sight. Once you know that, it’s impossible to walk through Paris without looking up at every gargoyle, angel and stone vine and wondering what it’s trying to tell you.

I also tracked down the house of Nicolas Flamel, the most famous alchemist in Paris and the man legend says discovered the philosopher’s stone. Built in 1407, it’s often called the oldest house in the city, and today it’s a restaurant. Yes, I touched the walls, just in case.

If the quest for eternal life fascinates you, you’ll also enjoy Silphium, Elixirs and the Quest for Eternal Life. And for more on the Knights Templar, whose story runs through medieval France, read The Templar Curse and Portugal’s Order of Christ.

What early readers are saying

⭐⭐⭐⭐⭐
“I loved THE ALCHEMIST’S CODEX! The fast pace of Eden’s adventures in multiple exotic locations is exciting, and the mystery plot is complex. It’s amazing how much of this book isn’t fiction but is written from Luke’s travels. I can’t wait to see what Luke brings us in the next Eden Black book.”

⭐⭐⭐⭐⭐
“It’s high adventure, danger and humour! I have read every one of Luke’s books, and each one combines his historical research and great storytelling. Every one is different and leaves you feeling you have learnt as well as been entertained.”

⭐⭐⭐⭐⭐
“Love the series, especially the action sequences, the characters, the dialogue and the settings. As Luke travels to the places he writes about, the descriptions in his books make you feel like you’re there. The Alchemist’s Codex is no exception, with Luke and his wife travelling through France to the locations in the book.”

⭐⭐⭐⭐⭐
“I absolutely adore this author. I’ve read every single one of his books, and having Eden Black and the team back in action has made my day. The Alchemist’s Codex is heavily based around France, Notre-Dame Cathedral and the legendary alchemist Fulcanelli. But not everything is as it seems. Another pulse-pounding thrill ride, with a fantastic bit of banter along the way.”

⭐⭐⭐⭐⭐
“Action-packed right from the start and full of great characters, many of whom we’re getting to know well. A great plot set in many locations, all portrayed vividly. A fantastic ride on another of Eden Black’s quests, with plenty of thrills and adventure to be had.”
