The Core of the Trilogy: A Book-by-Book Breakdown
Andrew Clements, an author renowned for his insightful school stories like Frindle, took a fascinating turn into the realm of young adult science fiction with this series. Each book centers on a different protagonist grappling with a unique and mysterious form of invisibility, exploring themes of identity, isolation, and human connection. Let’s break down each installment.
Book 1: Things Not Seen (2002)
This is the book that started it all, the one that introduced readers to a world where the laws of physics seem to have taken a strange holiday. Things Not Seen is a compelling blend of sci-fi mystery, teenage drama, and a thoughtful exploration of what it truly means to be seen.
The Story Unfolds
The novel introduces us to Bobby Phillips, a seemingly ordinary fifteen-year-old boy. His life takes a shocking and inexplicable turn when he wakes up one morning to discover he has become invisible. This isn’t a superpower; it’s a terrifying and isolating crisis. The story follows Bobby’s desperate attempts to understand his condition while navigating the immense challenges it presents. How do you eat? How do you move around? And most importantly, how do you keep a secret this massive from your parents, the school, and the government?
Bobby’s isolation is broken when he meets Alicia Van Dorn, a girl who is blind. Their connection forms the heart of the novel. For Bobby, Alicia is the only person who can “see” him for who he is, without the distraction of his physical appearance—or lack thereof. For Alicia, Bobby’s invisibility is irrelevant; she perceives the world and people through sound, touch, and intuition. Their budding relationship is a beautiful testament to seeing beyond the surface.
Unique Insights and Themes
- The Metaphor of Invisibility: Clements uses Bobby’s literal invisibility as a powerful metaphor for the feelings of alienation and being overlooked that many teenagers experience. It’s a clever device that makes a fantastical concept deeply relatable.
- Sensory Perception: The novel brilliantly explores the world from a non-visual perspective. Through Bobby’s new reality and Alicia’s everyday experience, readers are forced to consider how much we rely on sight and what we might be missing by doing so.
- Trust and Authority: A major conflict in the book involves Bobby’s parents trying to navigate a solution with government authorities. This introduces a layer of suspense and raises questions about institutional trust and the fear of the unknown.
Book 2: Things Hoped For (2006)
Published four years after the first, Things Hoped For expands the universe of the series. It introduces a new protagonist and a different facet of the invisibility phenomenon, shifting the focus from a personal crisis to a legacy of hope and a search for connection.
The Story Unfolds
Our new protagonist is seventeen-year-old Gwendolyn “Gwen” Locke. A talented violinist living in New York City, Gwen is preparing for a life-changing audition for a prestigious music conservatory. Her world is upended when her beloved grandfather, a retired physicist, disappears from their apartment. The only clue left behind is a cryptic note that leads her on a quest to find him.
Her search eventually leads her to Robert Phillips, the now-cured protagonist from the first book, and his family. More mysteriously, she encounters an invisible man who calls himself “Old Man” Bobby. This is Gwen’s grandfather. He reveals that his invisibility is a result of his own scientific experiments—a state he chose to enter. The plot becomes a race against time as Gwen must understand her grandfather’s complex scientific work to help him, all while grappling with the possibility of losing him forever.
Unique Insights and Themes
- Legacy and Choice: Unlike Bobby Phillips’s accidental affliction, Gwen’s grandfather chose his invisibility. This introduces a fascinating new dimension to the series, exploring themes of scientific responsibility, sacrifice, and the legacies we leave behind.
- The Nature of Hope: As the title suggests, the book is steeped in the theme of hope. It’s about holding onto hope in the face of impossible odds and finding strength in family history and human connection.
- The Elusive Sheila: This book deepens the mystery of a recurring character named Sheila, who appears to have a connection to the invisibility phenomenon and acts as a sort of clandestine guardian angel. Her role becomes more central to the overarching plot of the series.
Book 3: Things That Are (2008)
The final book in the trilogy, Things That Are, brings the series to a powerful and thought-provoking conclusion. It once again introduces a new protagonist but directly confronts the mysterious forces that have been operating in the background of the first two novels.
The Story Unfolds
The story is told from the perspective of Alicia Van Dorn, the blind girl from the first book. Now a confident and independent high school senior, Alicia has moved on with her life since her adventures with the invisible Bobby Phillips. However, the strange world of the unseen is not done with her. She begins to sense that she is being watched and followed by someone… or something.
Her instincts are right. The presence she feels is another invisible person, but this one seems different—more powerful and perhaps more dangerous. This new invisible individual is linked to the same shadowy organization and the mysterious Sheila from the previous books. Alicia is forced to step up and become the primary investigator, using her heightened senses and sharp intellect to uncover the truth behind the invisibility phenomenon and confront the “things that are” but cannot be seen. The story culminates in a direct confrontation with Sheila and a revelation about the true nature and origin of the invisibility technology.
Unique insights and Themes
- Perception vs. Reality: With a blind protagonist at its center, this book masterfully explores the theme of what is real. Alicia’s reality is not defined by sight, making her uniquely equipped to deal with a threat that exists outside the normal visual spectrum. The book challenges the reader’s own definition of reality.
- Empowerment and Agency: In the first book, Alicia was a crucial supporting character. Here, she takes center stage as a strong, capable hero. Her journey is one of empowerment, proving that her lack of sight is not a disability but a different, powerful way of experiencing the world.
- Resolving the Mystery: This novel finally pulls back the curtain on the overarching mystery. It provides answers about Sheila, the organization she works for, and why they are so invested in the people who turn invisible. It ties the threads of the previous two books together in a satisfying conclusion.
Understanding the Series Structure: A Thematic Trilogy
One of the most important things for new readers to understand is that the Things Not Seen series is not a traditional, continuous sequel series. You don’t follow one character’s journey across all three books. Instead, it’s best described as a thematic trilogy of companion novels.
Each book features a new protagonist and a self-contained plot. What binds them together is the shared universe, the recurring phenomenon of invisibility, and the mysterious presence of the character Sheila, who links the separate stories into a cohesive whole.
Do you need to read the books in order?
This is a very common question, and the answer is both yes and no, but mostly yes. Here’s why:
- You can read Things Not Seen as a standalone. The story of Bobby and Alicia is complete in and of itself and provides a fully satisfying reading experience.
- To understand the full scope, reading in order is highly recommended. The mystery surrounding the cause of the invisibility and the character of Sheila builds incrementally across the three books. Reading them out of order would spoil some of the reveals and lessen the impact of the overarching narrative. Things That Are, in particular, relies heavily on the reader’s knowledge of the events and characters from the first two books.
Think of it this way: each book is a puzzle piece. By itself, it’s an interesting picture. But when you put all three pieces together in the right order, you see the complete, stunning image that Andrew Clements intended to create.

Why Does the “Things Not Seen” Trilogy Endure?
What is it about this trilogy that captures the imagination? The appeal lies in how Andrew Clements grounds a fantastical premise in real, human emotion. The series isn’t just about the “cool factor” of being invisible; it’s about the profound human experience that this condition exposes.
The books ask deep questions that linger long after you’ve finished reading:
- What defines our identity? Is it how others see us, or how we see ourselves?
- How do we form genuine connections with others?
- What does it feel like to be truly alone, and how do we overcome that isolation?
By exploring these questions through the unique lens of invisibility, Clements created a series that is both a thrilling sci-fi mystery and a heartfelt story about growing up. The answer to “how many books are in the Things Not Seen series” is three, but the impact these three books can have is immeasurable. They offer a journey into the unseen parts of our world and, more importantly, into the unseen parts of ourselves.
