I think I may be in the minority on this one, but while I generally love the dark, thought-provoking works of M.R. Carey, I struggled to get into Once Was Willem. Granted, the novel was another testament to the author’s storytelling abilities, tackling a medieval horror fantasy told in a unique narrative voice. However, the style and structure of the book also made it difficult to parse at times, and this is something you have to get used to, or—if you’re like me—you just can’t.

Set in the mid-12th century, the story begins in a poor peasant village where the untimely death of a young boy named Willem leads his parents on a misguided attempt to bring him back. They turn to a powerful sorcerer named Cain Caradoc, who promises that he can help resurrect their son. However, what he failed to mention is that he will also be taking a piece of Willem’s soul as his price, and that the boy will come back as a grotesque shell of who he once was, becoming a monstrosity lingering between life and undeath. Horrified by the creature that once was their beloved son, his mother and father are joined by the rest of the villagers in driving Willem out.

Exiled, Willem makes his home in the surrounding woods, but he finds he is not alone. Others like him have taken refuge in the wilderness, among them individuals deemed oddities who have also been cast out—shapeshifters, elemental creatures, monsters, and spirits. Together, they form a band of seven to keep each other safe, eventually bringing the fight to Caradoc, whose nefarious plans have led him to set his sights on more than the souls of dead children. As the sorcerer’s magic threatens the villages and the residents turn to those they’ve cast out for assistance, Willem and his companions must confront the enemy in a final battle that not only determines the fates of the villagers but of the afterlife itself.

To be honest, although I appreciated the folklore and found family themes of Once of Willem, the book starts off slowly, and its ponderous pacing is further exacerbated by the archaic writing style. Indeed, the novel’s distinct narrative style is a double-edged sword, at once its greatest strength and greatest weakness. The story reads like a memoir told by Willem himself, but much like his physical body, his mind is also neither here nor there. He jumps around, meanders, inserting fragments of memory or asides at seemingly random places. Like the old-timey, period-appropriate prose, Willem’s voice makes this story feel authentic and immersive, but it is also very demanding on readers.

That said, Willem’s character arc is deeply moving, driven by his relatable need for acceptance and purpose. Afterall, everyone understands what it means to belong and to be accepted. It is universal, and it is human. Brought back to life only to be discarded by his own people, Willem also struggles with the meaning of his existence. Later, he finds solace in his group of companions that he meets in the wilderness. Bound not by blood but by a shared understanding, their camaraderie is truly the heart and soul of the story, bringing warmth and depth to an otherwise bleak tale. These characters shine whenever they are on the page, and unfortunately, their togetherness feels underused, making me wish we saw more of those connections.

In various reviews, I’ve seen Once Was Willem described as medieval Frankenstein meets The Magnificent Seven. Given its elements, I have to say these are good comparisons, and you should definitely check it out if you are interested in a unique blend of horror, folklore, and adventure. However, it can also be a frustrating read, especially if you prefer your stories to be more structured and organized. The dense prose can also present a challenge, and in fact, I found it more enjoyable after a while to switch to the audiobook, which made it easier to get into the story. Ultimately, I was glad I finished this, but it doesn’t quite reach the heights of M.R. Carey’s more readable books.
