Adversary to the Villain: A Cozy Fantasy Romantic Comedy (Assistant and the Villain Book 4)

HR Update: The position of “adversary to the villain” has been filled. Evie Sage does not recall applying.

Evie has always tried to be helpful, loyal, and only mildly involved in treason. But with a dangerous prophecy threatening the very magic of Rennedawn—not to mention the race to claim its necessary artifacts before King Benedict does—things are starting to feel…less like a career path and more like a serious problem.

The prophecy won’t stop pointing in Evie’s direction. The Villain’s magic keeps choosing her. And honestly, if you’re going to be accused of evil anyway, you might as well commit.

Unfortunately, the more Evie leans into her alleged villain era, the more her boss starts acting like the hero of a completely different story. Trystan is getting closer—closer than is wise, advisable, or even remotely professional—and looking at her like she’s already chosen a side. His.

Which is deeply inconvenient, because if Evie can’t save the kingdom’s magic, she might just become its greatest threat.

The hilarious fantasy romance series doesn't end at Adversary to the Villain! The thrilling conclusion to the series is coming soon!

Hannah Nicole Maehrer is a #1 New York Times bestselling author with a penchant for villains. She's primarily known for the Assistant and the Villain series and secondarily known for using humor to cope at inappropriate times —a strength in her day-to-day writing.

Before she was an author, she worked primarily in childcare and teaching emotions management. Ironically, her characters' emotions remain chaotic and unmanageable. Her work tends to mimic her life, which is made up of a very large, very loud, and very loving family, who remain her favorite characters and her primary source of inspiration in fiction. No matter how many years pass, from the time she read her first fairy tale, her passions have remained: romance, joy, laughter, and finding ways to incorporate them in everything she creates. hannahnicolemae.com

Adversary to the Villain begins with Evie Sage in a position she never expected to occupy. She has spent the earlier books as the cheerful, capable assistant to Trystan, the feared Villain of Rennedawn. Although Trystan's reputation suggests cruelty and darkness, Evie has gradually discovered that the man beneath the frightening title is much more complicated. Their relationship has developed from an unusual employer-employee arrangement into a deep emotional connection, even as circumstances repeatedly prevent them from openly embracing what they mean to each other.

Now, however, the rules have changed. Evie is no longer merely the Villain's assistant. A dangerous prophecy has begun to point directly toward her, and the magic of Rennedawn seems increasingly connected to her existence. At the same time, King Benedict is searching for powerful magical artifacts that could determine the future of the kingdom. What once seemed like a strange workplace romance has therefore become part of a much larger struggle over the kingdom's magic and destiny.

Evie's greatest problem is that the magic itself appears to be choosing her. She cannot simply walk away from the strange forces surrounding her, because they continue to pull her toward the prophecy. The more she learns, the more uncomfortable the truth becomes. The prophecy does not portray her as an innocent bystander. Instead, it suggests that Evie may have an important—and potentially terrifying—role in the destruction or transformation of Rennedawn.

This creates one of the book's central ironies. Evie has always been fundamentally kind. She is helpful, loyal, compassionate, and usually far more concerned about other people's well-being than her own. Yet circumstances increasingly place her in situations where behaving like the traditional heroine is impossible. If everyone is going to regard her as dangerous anyway, she begins to wonder whether she should simply embrace the role.

That is where Evie's gradual transformation becomes so interesting. She does not suddenly become evil. Rather, she begins experimenting with the idea of being powerful, intimidating, and willing to make difficult choices. Her growing confidence gives her a new edge, while her familiar humor keeps the change from becoming completely dark. She remains recognizably Evie, but she is no longer content to let other people decide what she is supposed to be.

Meanwhile, Trystan is experiencing a transformation of his own.

For much of the series, Trystan has been defined by his position as the Villain. His dark reputation, magical abilities, and willingness to do morally questionable things have made him the obvious figure to fear. But as the truth about his past and his connection to royal blood becomes clearer, that identity begins to unravel. Trystan is increasingly separated from the role everyone has assigned to him.

This produces a fascinating reversal. Evie, who began the series as the sunshine-filled assistant working for a villain, is moving closer to darkness. Trystan, who appeared to be the villain, is increasingly revealed to possess qualities associated with a hero. The title of the novel captures this reversal perfectly: the person who once stood beside the Villain may now become his adversary, while the Villain himself may no longer be the true villain at all.

The romantic relationship between Evie and Trystan remains at the heart of the story. Their attraction has never been the simple kind. They care for one another deeply, but fear, prophecy, magic, and questions of identity keep interfering. In this book, Trystan becomes increasingly drawn toward Evie even as circumstances make their relationship more dangerous.

He begins looking at her as though she has already chosen a side—and, from his perspective, that side is his. But the more the prophecy reveals about Evie's destiny, the more difficult it becomes for Trystan to know whether protecting her means standing beside her or protecting the kingdom from her.

The surrounding cast continues to provide much of the series' warmth and humor. Maehrer's world is deliberately playful, combining fantasy dangers with the absurdity of an office comedy. Characters who should behave like solemn figures from an epic fantasy often behave like eccentric coworkers or friends caught in an increasingly ridiculous workplace crisis. This lightness is important because the underlying story becomes progressively darker.

As Evie and the others investigate the prophecy, they discover that the mystery reaches much further back than they originally understood. The history of their families, their magical abilities, and the kingdom itself becomes relevant. The novel gradually reveals that the apparent divisions between heroes and villains have been misleading. People have inherited identities, powers, and expectations that may not actually belong to them.

One of the biggest revelations concerns Evie and Trystan's magical identities. Their parents had intervened in their childhood and switched their powers in an attempt to prevent an ancient destiny from unfolding in the expected way. The prophecy, however, has not been defeated. Instead, the characters eventually discover that the magical identities they thought they possessed are not what they believed. Evie is ultimately connected to the role of the true Villain, while Trystan's heritage points toward his being the rightful prince.

This revelation changes the emotional meaning of everything that came before. Trystan has spent his life believing himself to be the Villain, while Evie has spent hers believing herself to be an ordinary, kindhearted young woman who accidentally wandered into villainy. Their identities have effectively been reversed.

The climax brings these revelations into direct conflict. King Benedict's ambitions and the prophecy converge, forcing Evie into an impossible position. Rather than simply defeating an external enemy, she must confront the possibility that the greatest threat to Rennedawn may exist within herself.

The ending is deliberately unsettling. Evie ultimately finds herself captured and forced into Benedict's plans, apparently accepting a role she would previously have rejected. Trystan is left on the opposite side of the emerging conflict, creating the painful possibility that the couple who have spent the series moving toward each other may now be destined to become adversaries.

The novel therefore ends not with a comfortable romantic resolution but with a dramatic reversal of the series' original premise. Trystan may finally be stepping toward the heroic identity that was always hidden within him, while Evie is pushed toward the villainous destiny that the prophecy seems to demand.

Yet the story leaves room for hope. Evie has repeatedly demonstrated that destiny does not automatically determine character. She has spent the series choosing kindness even when surrounded by violence, and Trystan has repeatedly shown that his actions cannot be reduced to the title of "Villain." Their identities may have been switched, but their choices remain their own.

Ultimately, Adversary to the Villain is about the danger of labels and the complicated relationship between destiny and free will. It asks whether someone becomes a hero or villain because of their blood, their magic, their title, or their choices. Evie and Trystan have spent the entire series trying to understand who they really are, and this book forces them to confront the most frightening answer: perhaps they have been fighting against the wrong versions of themselves all along.

The book leaves the central romance and the fate of Rennedawn unresolved, setting up the forthcoming fifth and concluding installment.
