Lightlark is generally a solid fit for ages 13 and up, but because it sits squarely in the "Romantasy" genre, it carries more romantic heat and "deadly trial" violence than your typical middle-grade fantasy. If your teen is already deep into BookTok, they’ve likely seen the hype, but you should know it’s definitely a step up in maturity from something like Percy Jackson.
TL;DR: Lightlark by Alex Aster is a high-stakes YA fantasy rated for ages 13+ that blends Hunger Games-style competition with the "steamy" romantic tension typical of modern BookTok hits. While the content is less explicit than "New Adult" series like A Court of Thorns and Roses, it contains moderate fantasy violence and suggestive themes that make it best for mature middle schoolers and high schoolers.

If you feel like you’ve been seeing this gold-and-black cover everywhere since 2022, you aren't imagining it. Lightlark is a viral phenomenon written by Alex Aster, who essentially pioneered the "pitch a book on TikTok" marketing strategy.
The story centers on the Centennial, a deadly game held every 100 years on an island called Lightlark. Six rulers of six different realms—each cursed in a unique, usually terrible way—compete to break their curses. The catch? One ruler has to die for the curses to be lifted. Our protagonist, Isla Crown, is the ruler of Wildling, and she’s hiding a massive secret that could get her killed instantly.
As we hit April 2026, the series is reaching its fever pitch with the final installment of the trilogy. It’s the kind of "event" reading that has teens (and plenty of adults) camping out at bookstores or refreshing their Kindles at midnight.
The appeal of Lightlark isn't just the magic; it’s the "vibes." Alex Aster knows exactly what her audience wants:
- The "Love Triangle": It features heavy romantic tension between Isla and two very different male leads (Grim and Oro).
- The Aesthetic: The world-building is lush and visual, which is why it translates so well to social media edits.
- The Twists: It’s built on "betrayal" tropes. In a world where everyone is a liar, the "who can I trust?" hook keeps pages turning.
According to Screenwise community data, about 42% of 9th and 10th-grade girls have Lightlark or its sequel, Nightbane, on their reading lists. It’s a major cultural touchstone for the current generation of readers.
When we talk about the "age rating" for a book like this, we have to look at three main pillars: violence, romance, and complexity.
The "Spice" Factor (Romance)
This is usually the #1 question parents ask. Is it "spicy"? In the world of BookTok, "spice" refers to explicit sexual content. Lightlark is firmly Young Adult (YA), not New Adult (NA). This means:
- Heavy Tension: There is a lot of "yearning," smoldering looks, and suggestive dialogue.
- Moderate Heat: There are kissing scenes and some "on-page" making out that gets reasonably intense, but it generally stops before things become graphic.
- The Sequel Note: Be aware that the second book, Nightbane, dials up the romantic intensity slightly more than the first.
Fantasy Violence
The Centennial is a death match. You’re going to see:
- Magical Combat: Think elemental powers, shadow magic, and swordplay.
- Character Deaths: Because the stakes involve one ruler dying, there is grief and some semi-graphic descriptions of injuries and combat.
- The "Grim" Factor: One of the realms is literally called Nightshade, and the themes of death and darkness are prevalent.
Complexity and Themes
The book deals with themes of worthiness, deception, and the burden of leadership. It’s not a "difficult" read in terms of vocabulary, but the emotional manipulation between characters requires a bit of maturity to navigate.
We give Lightlark a WISE score of 78. It scores high on Engagement (it’s a genuine page-turner) and Cultural Literacy (it's the "water cooler" talk of the teen world right now), but slightly lower on Educational Value—this is pure popcorn entertainment, not a deep literary masterpiece. And honestly? That’s okay.
If your teen has finished the series and is looking for something similar—or if you think Lightlark is a bit too much for your 11-year-old—here are some Screenwise-approved pivots:
- For the 11-12 set (Lower Spice): Try The Hunger Games for the "deadly trial" vibe or Amari and the Night Brothers for a magical competition that’s more age-appropriate.
- For the 15+ set (More Mature): If they liked the romance and the high stakes, they’ll likely move toward Fourth Wing, but be warned: that one has significantly more "spice" and graphic content.
- Gaming Parallel: If they love the "ruler of a realm" vibe, they might actually enjoy Stardew Valley (for the cozy realm-building) or Zelda: Breath of the Wild for the high-fantasy adventure.

Instead of just checking the rating and handing it over, use Lightlark as a bridge to talk about how they consume media:
- "What’s the 'vibe' on TikTok about this book?" This helps you understand the community they're engaging with.
- "The rulers in this book are all keeping secrets. Do you think Isla is a 'good' person for lying to save her people?" This gets into the moral gray areas the book loves to play in.
- "How does the romance in this book compare to what you see in real life or other shows?" A great way to talk about "theatrical" vs. "healthy" relationships.
Q: Is Lightlark appropriate for a 12-year-old?
It depends on the 12-year-old, but it’s on the "older" side of the line. If they’ve read and handled the later Harry Potter books or The Hunger Games, they’ll likely be fine, but you may want to discuss the romantic themes with them.
Q: Does Lightlark have any "trigger warnings"?
The book contains fantasy violence, descriptions of blood/wounds, character death, and themes of betrayal and emotional manipulation. There are also references to curses that cause physical and emotional pain.
Q: Is there a movie version of Lightlark?
Yes, a movie is currently in development with Universal and the producers of Twilight. As of early 2026, we're still waiting on a firm release date, but the hype is only going to grow as the film gets closer.
Q: How "spicy" is the romance?
On a scale of 1 to 5 (with 1 being Frozen and 5 being Fifty Shades), Lightlark is about a 2.5. There is heavy romantic tension and some descriptive kissing, but it stays within the boundaries of traditional Young Adult fiction.
Lightlark is the quintessential "BookTok" book. It’s fast, it’s dramatic, and it’s a little bit "extra." For most teens 13 and up, it’s a fun, engaging fantasy that encourages reading in an era of short-form video. It isn't high literature, but it’s a cultural moment. If your teen is reading it, they're in good company—just be ready for them to ask for the sequel the moment they finish the final page.
