The Search for WondLa Reading Level: A Complete Guide

What Reading Level Is The Search for WondLa?

The Search for WondLa has a Lexile of 760L and an ATOS level of 5.2, with grades 4–8 placement from TeachingBooks. These scores are consistent with a mid-fifth-grade independent reading level — lower than the Spiderwick Chronicles (Lexile 600L, ATOS 4.2) despite being a more complex and longer book, reflecting that DiTerlizzi’s prose in this series is somewhat more accessible than the atmospheric, compressed prose of the Spiderwick novels. At 74,098 words and approximately 477 pages, it is a substantial middle-grade novel that most independent readers in grades 4–6 will complete in two to three weeks.

The book’s illustrated format — DiTerlizzi’s two-color spot art and full-page illustrations appear throughout — gives it a more accessible feel than a purely prose novel of the same length, and the science fiction world-building, while rich, is introduced gradually through Eva’s own discovery process rather than front-loaded. This makes it more accessible for readers who are new to science fiction than many books at this reading level. For official Lexile and AR scores, visit Lexile.com or AR BookFinder. ReadingVine’s assessments are independent editorial judgments.

What Age Is The Search for WondLa Appropriate For?

We recommend The Search for WondLa for readers ages 9–14, grades 4–8. The primary content consideration worth noting for parents:

Beyond this, the content is standard adventure-level peril: a dangerous alien world, a marauding villain huntsman, wilderness survival. Nothing graphic or disturbing beyond what is typical for the genre. DiTerlizzi describes the book as appropriate for ages 10 and up; motivated nine-year-olds handle it without difficulty.

What Is The Search for WondLa About?

Eva Nine has spent her entire twelve years underground, in a sanctuary maintained by her robot caretaker Muthr. The sanctuary runs training simulations, teaches Eva survival skills, and provides holographic images of the world above — but Eva has never been outside. She has never seen the real sun. She has never met another person. Her most treasured possession is a battered scrap of cardboard depicting a child, an adult, a robot, and the fragment of two words: “Wond” and “La.” She does not know what it means or where it came from.

When the huntsman Besteel discovers and destroys the sanctuary, Eva is forced aboveground for the first time. The world she finds is nothing like the holograms: Orbona is an alien landscape of bioluminescent plants, tentacled creatures, floating creatures, alien beings of dozens of species, and no humans visible anywhere. Eva is equipped with an Omnipod — a sophisticated information device — that can identify species, translate languages, and provide information, but that is itself a product of the human civilization she cannot find.

Eva gradually gathers companions: Rovender Kitt, a tall, blue alien who becomes a reluctant ally and eventually a true friend; and Otto, a large water-bear-type creature who serves as transport and protection. Together they travel across Orbona’s strange landscapes, pursued by Besteel, searching for other humans. The journey eventually leads to an ancient buried building — the New York Public Library — whose functioning computers identify Eva’s treasured scrap of cardboard. The “WondLa” is not a word but a fragment: the cover of The Wonderful Wizard of Oz, by L. Frank Baum. Orbona, it emerges, is not an alien planet but Earth — a version of Earth that died and was reborn. The humans Eva is searching for are there. And a human boy named Hailey arrives at the book’s end to take her to them.

The Wizard of Oz Connection

DiTerlizzi has said that The Wizard of Oz was among his primary inspirations for the WondLa trilogy, and the parallels are both structural and specific. Eva Nine, like Dorothy Gale, is a girl who has been living in a limited and sheltered environment (underground/Kansas) and is thrust into a strange, vivid, alien world (Orbona/Oz). She gathers companions who each represent something she needs: Rovender for wisdom, Otto for physical protection. She is pursuing something she believes will take her home, following a clue that turns out to mean something different than she thought. And the word “WondLa” itself is ultimately revealed to be a fragment of “The Wonderful Wizard of Oz” — the clue was the answer all along, and it pointed back to a book.

The Oz allegory is the book’s most productive classroom discussion topic, and DiTerlizzi’s author’s note invites this conversation directly. He describes the book as his attempt to honor the tradition of classic children’s literature by finding the version of it that would have been written for a reader in 2010 — the same sense of wonder, discovery, and longing for home, in a world shaped by science fiction rather than fantasy. Eva’s WondLa is Dorothy’s ruby slippers: the object that means home, that contains more than it appears to, that is the key to everything without the character initially understanding why.

DiTerlizzi’s Illustrations in WondLa

The WondLa trilogy features DiTerlizzi’s illustrations throughout — not the pen-and-ink style of the Spiderwick Chronicles but a two-color digital painting approach that gives Orbona’s alien creatures the quality of natural history illustrations from a planet no naturalist has yet visited. The creatures are rigorously designed: each species has a consistent visual logic, detailed anatomy, and the kind of biological specificity that rewards readers who slow down to look. The full-page illustrations function as chapter dividers and scene-setters; the spot art appears in the margins and within scenes, giving the book the visual density of an illustrated novel rather than a prose novel with pictures.

DiTerlizzi has said that he designed the WondLa world’s creatures with the same attention he brought to his Dungeons & Dragons illustration work — each species has a defined ecology, behavior pattern, and visual identity. The book’s website, launched with the original 2010 publication, included an augmented reality feature that allowed readers to point a webcam at the book’s illustrations and see the creatures animated in three dimensions — an early example of integrated digital-physical publishing that was remarkably ambitious for its time.

The Search for WondLa Themes and Lessons

The book’s environmental argument — that Earth died and was reborn as Orbona, a planet populated by alien creatures who are in some sense Earth’s heirs — is the trilogy’s most sustained thematic claim. Humanity’s absence from Orbona is a consequence of human behavior; Orbona’s alien biodiversity is what Earth became after humans were no longer there to dominate it. Eva’s search for other humans is simultaneously a search for her species’ place in a world that has moved on without them — and the subsequent volumes complicate this search considerably, as Eva discovers that the surviving humans of New Attica have not learned the lesson that Orbona’s rebirth represents.

The question of what makes a family — specifically, whether a robot who loves you is really your mother — is the book’s most intimate argument and the one that children most consistently engage with. Muthr is not programmed to love; she is programmed to care for. The distinction blurs across Eva’s first twelve years, and when Muthr dies, the question of what exactly has been lost is genuinely complex. The book does not resolve it: it holds the ambiguity and lets Eva hold it too.

Discussion questions for classrooms and families: What does the word “WondLa” turn out to mean — and how does knowing this change the whole book? Was Muthr Eva’s mother? What is the difference between being programmed to care and actually caring? What does Orbona’s existence tell us about what happened to Earth? If you woke up in an alien world with only an Omnipod and one companion, who would you want that companion to be?

The Search for WondLa on Apple TV+ (2025)

An animated series adaptation premiered on Apple TV+ on June 28, 2025, produced by Skydance Animation with DiTerlizzi as executive producer. The series features the voice of Jeanine Mason as Eva Nine, with Teri Hatcher, Brad Garrett, Alan Tudyk, and D.B. Sweeney in supporting roles — Teri Hatcher, who narrated the audiobook of the original novels, bringing her voice back to the WondLa world in a new form. The animated visual style brings DiTerlizzi’s creature designs to motion, and the series is the first major streaming adaptation of his work. Families who love the book will find the series a current and vivid companion; viewers who discover the series first are reliably sent back to the books.

The WondLa Trilogy

The WondLa series is a complete trilogy: The Search for WondLa (2010), A Hero for WondLa (2012), and The Battle for WondLa (2014). The three books should be read in order; each builds directly on the previous one, and the trilogy as a whole tells Eva’s complete story from underground isolation to the resolution of Orbona’s human-alien conflict. The second book introduces New Attica and its controlling administrator Cadmus Pryde; the third resolves the trilogy’s central conflict over coexistence between humans and Orbona’s alien inhabitants. All three feature DiTerlizzi’s illustrations throughout and are available as a boxed set.

About Tony DiTerlizzi

For a full biography of Tony DiTerlizzi, including his Dungeons & Dragons work, his Caldecott Honor for The Spider and the Fly, and his collaboration with Holly Black on the Spiderwick Chronicles, see our Spiderwick Chronicles guide. The WondLa trilogy represents DiTerlizzi’s first major solo authorial project — his earlier work as a sole creator was primarily picture books, while the Spiderwick novels were co-written with Black. The WondLa series allowed him to build a world entirely from his own imagination, and the result is his most personal and most ambitious work.

DiTerlizzi has said that WondLa grew from two sources: his love of classic children’s literature — specifically the Wizard of Oz tradition — and his concern about environmental degradation and humanity’s relationship to the natural world. The vision of Earth reborn as Orbona after humanity’s disappearance is his most explicit environmental argument, and the second and third books develop it considerably as Eva discovers that the surviving humans of New Attica have not changed the patterns that destroyed the original Earth. The Apple TV+ animated series, which premiered in June 2025, is the most significant adaptation of his work since the 2008 Spiderwick feature film.
