Stephanie Garber has basically cornered the market on fantasy that feels like a fever dream. If you’ve noticed your teen carrying a book with a literal broken heart on the cover, this is it. It’s the first in a trilogy that spun off from her Caraval series, but you don’t need to have read Caraval, Legendary, or Finale to jump in here.
The story follows Evangeline Fox, a girl who makes a deal with Jacks, the Prince of Hearts, to stop the love of her life from marrying someone else. It’s a classic "deal with the devil" setup, but flavored with sugar-coated magic that hides some fairly sharp teeth.
The BookTok of it all
If your kid is on the reading side of social media, they’ve seen this book. It’s the poster child for the "aesthetic" fantasy movement. We aren't talking about gritty, map-heavy world-building with invented languages. This is about magic that smells like apples and heartbreak, and characters who wear elaborate gowns while making terrible life choices.
For parents, the win here is that it’s remarkably safe for how much tension it generates. In a market where many young adult books are secretly "New Adult" (which is code for "there is a very graphic scene on page 200"), Garber keeps things firmly in the realm of yearning and intense eye contact. If you’re wondering exactly where the line is drawn, our parent's guide to Once Upon a Broken Heart breaks down the specific "spiciness" level, which stays low despite the heavy romantic themes.
Why it sticks the landing
Most fantasy novels for this age group fall into two traps: they’re either too dense or too predictable. Garber avoids both by leaning into "fairy tale logic." In this world, rules are meant to be broken, and the "wicked" characters aren't always the ones you expect.
The 4.2 rating on Amazon isn't just from hardcore fans; it’s because the pacing is relentless. Each chapter ends on a hook that makes "just one more" a lie every kid tells themselves at 11:00 PM. It’s a great pick for "reluctant readers" because the prose is accessible and the stakes are immediately personal. It’s not about saving the kingdom; it’s about saving your own heart, which is a much more compelling hook for a thirteen-year-old.
The Jacks factor
The Prince of Hearts is the engine of this series. He’s the quintessential "morally grey" character. He’s manipulative, selfish, and potentially dangerous, but he’s written with enough charm that readers keep coming back.
This is a perfect opportunity to talk about boundaries. Evangeline spends a lot of the book being gaslit or manipulated by immortal beings. It’s not "toxic" in a way that ruins the story, but it’s definitely a theme worth noting. If your kid loved the high-stakes drama of the author's previous work, they’ll find the same DNA here, just with a more focused, romantic lens.
One heads-up: the ending is a cliffhanger. If they finish this one, be prepared to have the sequels ready, or you'll be making a late-night trip to the bookstore.
