It is a lot. Honestly, when Deborah Harkness released the second installment of the All Souls Trilogy, Shadow of Night, it felt like a massive gamble. Middle books are notorious for "sagging." They usually just move characters from point A to point B to set up a finale. But instead of a bridge, Harkness built a time machine. She took Diana Bishop and Matthew Clairmont out of the modern comforts of Oxford and slammed them into the grime, politics, and absolute danger of 1590s London.
Most readers expected more of the same "forbidden romance" vibe from A Discovery of Witches. What they got was a dense, meticulously researched Elizabethan thriller that happens to have vampires and witches in it.
The book is thick. It’s heavy. It’s intimidating. If you’ve ever tried to explain the plot to someone who hasn't read it, you probably sounded like a conspiracy theorist. You’ve got the School of Night, alchemy, the Holy Roman Empire, and a very grumpy Matthew Roydon. It shouldn't work, but it does.
The Reality of Time Walking in Shadow of Night
Time travel in fiction is usually clean. A portal opens, you step through, and you’re wearing the right clothes. Not here. In Shadow of Night, the transition is visceral. Diana Bishop doesn't just "arrive"; she is a woman out of time in a world that genuinely wants to kill her for being different.
Harkness, who is a real-life historian and professor, uses her expertise to show how terrifying the past actually was. It wasn't just about the lack of indoor plumbing. It was the lack of agency. Diana goes from being an acclaimed historian to a "wife" who has to navigate a world where her intelligence is a liability.
The 1590 setting isn't just window dressing. It's the engine of the story. Matthew isn't the same man in the 16th century. He’s darker. He’s more violent. He’s "Matthew Roydon," a member of the Queen’s secret service and a philosopher with a mean streak. Seeing Diana realize that the man she loves is actually a product of a much more brutal era is where the real tension lives. It’s not just about the Congregation chasing them through time; it’s about whether their relationship can survive the weight of Matthew’s past—which is now their present.

Why the School of Night Matters
You might think the "School of Night" is just a cool, edgy name Harkness made up. It’s not. It was a real-life circle of Elizabethan intellectuals, poets, and scientists. We’re talking about heavy hitters like Christopher Marlowe, Thomas Harriot, and George Chapman.
In the world of the All Souls Trilogy, these men weren't just drinking buddies. They were part of Matthew’s inner circle.
- Christopher "Kit" Marlowe: In the book, he’s a daemon. It explains his brilliance and his legendary volatility perfectly. His obsession with Matthew adds a layer of jealousy that makes the London scenes feel incredibly claustrophobic.
- Thomas Harriot: The mathematician. He represents the bridge between magic and science, which is the heartbeat of the entire series.
- Mary Sidney: The Countess of Pembroke. She’s one of the few people Diana can actually relate to, and their chemistry as female intellectuals in a restrictive society is one of the book’s highlights.
Basically, Harkness populates the story with people who actually existed, but she gives them "supernatural" explanations for their real-world genius. It makes the world feel lived-in. When Diana meets Queen Elizabeth I, it isn't a "YASS Queen" moment. It’s a terrifying encounter with a monarch who is aging, paranoid, and incredibly dangerous. It's high-stakes politics where one wrong word means the Tower of London.
The Alchemical Marriage and the Ashmole 782 Mystery
The whole reason they went back was to find Ashmole 782, the enchanted manuscript. But the book becomes a hunt for more than just paper. It’s about the "Alchemical Marriage."
Alchemy is confusing. Let's be real. Most of us think it's just turning lead into gold. In Shadow of Night, it’s a metaphor for the union of Diana and Matthew. The chemical wedding. The sun and the moon. The series uses actual alchemical imagery from the 16th and 17th centuries—like the Rosarium Philosophorum—to mirror Diana’s growth in her power.

She isn't just learning "spells." she’s learning how to weave reality. The introduction of the "weaving" concept changed the game for how witches are portrayed in the series. It moved away from generic magic and toward something more fundamental and elemental.
The Prague Chapters: A Shift in Tone
About halfway through, the setting shifts to Prague and the court of Rudolf II. If you thought London was intense, Prague is a fever dream.
Rudolf II was a real Holy Roman Emperor who was obsessed with the occult. He collected "wonders" in his Cabinet of Curiosities. Harkness leans into the surrealism of this court. It’s where Matthew’s father, Philippe de Clermont, looms largest, even when he isn't physically there. The psychological toll on Matthew in these chapters is brutal. We see his "blood rage" not as a cool superpower, but as a degenerative, terrifying illness that threatens to consume his identity.
Common Misconceptions About Shadow of Night
People often get frustrated with the pacing. They want more action and less "Matthew being moody in a library." But that misses the point.
- It’s not a romance novel disguised as history. It’s a historical novel with a romance at its core. If you skip the descriptions of 16th-century life, you lose the reason why Diana is changing.
- The "Slow" Middle: Many readers struggle with the first 200 pages in London. It’s meant to feel stagnant. Diana is stuck. She’s waiting. She’s learning. Once they hit Sept-Tours and then Prague, the velocity changes completely.
- The Father Figure: Philippe de Clermont is often seen as a villain or a hero. Honestly? He’s neither. He’s a bronze-age warlord trying to ensure the survival of his species. His "testing" of Diana is cruel, but in his mind, it’s necessary.
The Actionable Takeaway for Readers
If you are diving into Shadow of Night for the first time, or if you’re doing a re-read before the next spinoff comes out, do yourself a favor: look up the art.

When Harkness describes a specific alchemical drawing or a piece of jewelry, it usually exists. Looking at the real Ashmole manuscripts or portraits of Mary Sidney while you read makes the experience 10x more immersive.
The book isn't just a story; it’s a puzzle. The "Shadow of Night" title refers to a poem by George Chapman, and the themes of darkness, light, and hidden knowledge are woven into every chapter.
To truly appreciate what Harkness did here, you have to stop waiting for the plot to "happen" and start living in the atmosphere. The book demands your attention. It doesn't do "light reading." But for those who stick with it, the payoff in the final third—especially the revelations regarding Diana’s lineage and the true nature of the book of life—is unparalleled in the genre.
Stop treating it like a sequel. Treat it like an immersive historical simulation. Pay attention to the "weaving" lessons Diana takes with Goody Alsop. Those moments aren't just filler; they are the technical manual for how the rest of the trilogy—and the entire All Souls universe—actually functions. Understanding the "threads" is the only way to understand where the story goes in The Book of Life and Time's Convert.
Focus on the transition of Diana from a scholar who studies history to a woman who makes it. That’s the real arc. Everything else—the vampires, the time travel, the ancient blood feuds—is just the backdrop for a woman finding her own voice in a century that wants her to stay silent.
