If you are a fan of the epic fantasy worlds of Tomorrowland, get ready for a new adventure. The world-famous music festival is dropping the second book in its massive fantasy series, and it’s called The Sky of Sacrifice. This isn’t just merch. It’s a core part of Tomorrowland’s plan to build a story universe that goes way beyond the festival grounds. 1
For years, the team behind the festival has been creating a deep lore based on themes of unity, love, and hope. Now, they are bringing that lore to life through
The Book of Wisdom Trilogy. The first book, The Great Library of Tomorrow, came out in 2024, and The Sky of Sacrifice is the next chapter. This is a global release, with major publishers like Blackstone Publishing in the US and Text Publishing in the UK and Australia making sure it gets into the hands of fantasy readers everywhere. 2
What’s the Story About?
So, what can you expect from The Sky of Sacrifice? The story picks up after the big bad from the first book, the Ash Man, has been defeated. Things seem peaceful, and the main character, Nu, is settling into her role as the Sage of Truth and has even found love.
But that peace doesn’t last long. Nu is hit with terrifying nightmares that feel like a warning of a new evil on the rise. A “savage act” shatters the calm at the Great Library, and the heroes realize they have to split up to face this new threat. Nu and her friend Robin go on a quest to find a mysterious figure from the past, while another hero, Veer, travels to a realm of total darkness and despair. The book’s tagline says it all: “When secrets cause sacrifice, friendships will be tested”. Expect tough choices, high stakes, and a story that explores the real cost of being a hero. 3
The Two Types of Tomorrowland Books
If you’re new to the Tomorrowland literary world, you might be a little confused. There are actually two different types of books, and they work together.
First, you have the annual festival tie-in novels. These are standalone books that tell the origin story of that year’s festival theme, like The Rise of Adscendo (2023) or The Spirit of Life (2024). They are cool collector’s items that give you the backstory for the Mainstage and everything you see at the festival.

Then you have the main event: The Book of Wisdom Trilogy. This is the epic fantasy series that The Sky of Sacrifice is part of. It’s the foundation of the entire Tomorrowland universe, introducing core ideas like the Great Library, the different realms of Paperworld, and the Sages who protect them. The two series connect, so things you read about in a festival book might show up in the main trilogy, creating a super rich and interconnected world for dedicated fans.
Who Is the Author, Rosalia Aguilar Solace?
One of the coolest parts of this series is the mystery around the author, Rosalia Aguilar Solace. Her official bio says she’s from a family of writers in Mexico City and that she literally splits her time between our world and the magical Great Library of Tomorrow.
It’s a great story, but here’s the secret: Rosalia Aguilar Solace is actually a pseudonym for the creative team at Tomorrowland. They created a fictional author who is a character in her own universe to make the whole experience more immersive. It’s a clever move that blurs the line between fiction and reality, and they even have “her” do interviews in character.
What Are Fans and Critics Saying?
The series has earned high praise from professional reviewers. Bestselling author C.S. Pacat loved the “atmosphere and the fantasy of spending your days in a library,” while others have called it an “epic tale full of hope and light and wonder”. 4
The fan community on sites like Reddit has a more detailed take. Many book-loving festival-goers say the novels add an “extra dimension to the festival,” making the stage designs and themes “make more sense”. For them, the books are essential reading to get the full Tomorrowland experience. 5
However, many fans agree on one point of criticism: the writing style. Readers have called the prose “unnecessarily hard to get into” and “written really complicated”. Some say it’s a “struggle to get through the first 80 pages or so” because of all the new jargon and complex sentences. This feedback comes from both native and non-native English speakers, showing it’s a common hurdle. One early reviewer for the new book felt it was caught between being a Young Adult and an adult novel, suggesting it could be improved by picking a lane . 6
