12 Young Adult Sci-Fi and Fantasy Series You Should Try

Remember when we talked about how a sci-fi/fantasy series lets the heroes grow up with its readers? Well, a little thing like death isn’t going to stop Walker Callaghan, the heroine of C.L. Gaber’s Ascenders Saga, of doing just that. When Walker dies at the age of 17, she arrives at a place called The Academy. The only thing the people there share in common is that they all were on the morning announcements of their local high schools because they died young. 

Now, Walker must navigate not only the realm of the dead, but also the strangely familiar dynamics of high school. There might not be any tests or SATs, but there are still cliques, classes, and of course crushes. 

The story only evolves from there, and Walker learns more about The Academy, The Other, the Mist, and all sorts of imaginary afterlifes while she searches for a place she can truly call home. 

Enemies become lovers in this New York Times-bestselling YA romantasy series, featuring the witch Fritzi and witch hunter Otto. However, Otto is secretly a double agent, plotting his revenge against the people who burned his innocent mother alive. 

Fritzi and Otto form a reluctant truce to take down Kommandant Dieter Kirch, the leader of the witch hunters. But what they find along is more horrifying and compelling than they ever imagined. 

“Set against the backdrop of the Medieval German Witch Trials, Raasch and Revis weave a fantasy and heart-pounding tale full of history, love, witchcraft, and war that will have you gripping your book, waiting for the next shocking twist,” says Jennifer L. Armentrout.

The Legacy of Orïsha isn't just a classic fantasy for young adults … it's also written by a young adult. Author Tomi Adeyemi made her debut with Children of Blood and Bone when she was just 24 years old, and the book was an instant hit, debuting at #1 on the New York Times bestsellers list. 

The story follows the teenage Zélie Adebola in the fictional land of Orïsha (influenced by West African culture and lore) as she looks to bring back magic and strike against the monarchy. To do it, Zélie will need the help of a rogue princess and the resilience to outrun destructive princes, to survive vengeful spirits, and to control both per powers and her feelings for the enemy. 

Both Children of Blood and Bone and its sequel, Children of Virtue and Vengeance, were selected by TIME as among the 100 best fantasy novels of all time. The conclusion to the trilogy, Children of Anguish and Anarchy, is set for publication on June 25.

This YA fantasy trilogy, which Publishers Weekly called “a wonderfully satisfying magical saga” in its starred review, follows a mage called Iolanthe Seabourne, the Chosen One who is prophesied to defeat the Bane. Taking down a tyrant would be an impossible task for anyone, let alone a 16-year-old girl with no training, but Iolanthe has no choice but to press forward.

Her most ardent supporter is her protector, Prince Titus, who has sworn to defend her and earn vengeance against the Bane. He never expected to fall in love with the girl, but soon he must choose between his mission and her life. 

The Fever Crumb Trilogy begins with London on the brink of the apocalypse and follows orphan Fever Crumb. Fever’s engineering mind might just be able to save humanity, but only if she can figure out who to trust and how to survive the threats all around her. 

If you love Fever’s saga and want to continue to read more books in the same world, you can always move on to Philip Reeve’s Mortal Engines series, which was eventually turned into a Peter Jackson film. The Fever Crumb Trilogy takes place in the same world but acts as a prequel series (though it’s set many, many years before). 

If you’re a fan of The Hunger Games, you’ll love this series by Pierce Brown (the latest installment of which, Light Bringer, published earlier this year). While some would argue the book is stylistically more like an adult novel, the tropes within read more like YA in our opinion. Not only does the story begin with a battle royale, but that battle serves a second function as a school for battle, where the elites learn to fight against one another.

In this sci-fi series, the cosmos have been stratified by castes marked with colors. Red is the lowest caste, while Gold is the highest. When Darrow, a Red in search of revenge, manages to infiltrate the Gold’s highest rungs, his deceit and cunning cause all sorts of problems for his enemies, his friends, and especially Darrow himself. 

Author Edith Pattou introduced readers to her heroine Rose in 2012. In East, an enormous white bear appears and offers Rose a chance to go on a grand journey. When mistakes derail her plans, however, Rose is forced to choose between returning to the safety of her home or going on a dangerous quest to fix what she broke. 

The series, which has drawn comparisons to Beauty in the Beast, continued in 2018 with West. While we won't go into the plot to the second entry in the duology, for fear of spoiling Book 1, here's what bestselling author Tamora Pierce had to say about it: “I could hardly breathe … there isn't a dull moment.”

Brandon Sanderson might be best-known for his work in the epic fantasy space, but with Skyward, he displays his talent for science fiction. The plot revolves around 17-year-old Spensa, or Spin, who longs to be a pilot and stumbles upon a broken-down, ancient ship in a world beaten down by alien starfighters. 

If she can fix up the ship, there's a chance to achieve both her dream and her freedom. But being a pilot—being a hero—isn't all that it seems. Grappling with expectations and navigating difficult choices, the Skyward series includes four primary books with all sort of other adventures stuffed in-between, so you can read as much about Spin and Sanderson's created world as your heart desires.

Gena Showalter might be better-known for her romantasy stories, but she’s no stranger to the YA space, either. Her White Rabbit Chronicles offer a zombified retelling of Lewis Carroll’s Alice in Wonderland books, while the Everlife trilogy takes a look at life after death. In Showalter’s world, death is only the beginning, for a first life is followed by what’s known as the “everlife,” where two factions war against each other for dominance. The series follows 17-year-old Tenley as she decides not only where she wants to go in the afterlife, but how she wants to contribute to what feels like a never-ending war. 

If you think breakups are hard, try doing it during an alien invasion. In the year 2575, Kady and Ezra must evacuate their home and face down a mutating plague. They'll have to work together if they want to survive … too bad they can hardly stand to look at each other. 

A series of epistolary novels, the three books in The Illuminae Files are told through a fascinating collection of emails, instant messages, transcripts, and more fascinating documents that maintain an air of mystique and a sense of discovery perfect for science fiction.

This Ravenous Fate by Hayley Dennings explores a fantasy version of Jazz Age Harlem where vampires roam the streets. Eighteen year-old Elise Saint's family runs a thriving vampire-hunting business, but she's not so sure she wants to follow in her family's footsteps. 

But what happens when the vampires start turning back into mortal humans? How is Elise's old friend, Layla, involved? Old betrayals and bitterness arise as Elise and Layla investigate a string of brutal killings that might just threaten humans and vampires alike.

The first book in the planned duology debuted in August of 2024, and bestselling author Gabi Burton calls it “sweetly vicious.”

Where the Fever Crumb Trilogy takes place in a future version of London, Alexandra Harvey takes readers back to the past of 1814 London society. When three cousins (Emma, Gretchen, and Penelope) are gifted with powers of witchcraft, they find new strength. They also find themselves the target of a coven whose members gain power from killing young witches. 

Each of the three cousins get a chance to shine in this trilogy, as each book places a spotlight on one book. The first in the series, The Secret Witch, it’s Emma who takes center stage. Next is Gretchen in The Whisper Witch, followed by Penelope’s turn in The Bone Witch. So, regardless of which of the three cousins you find yourself relating to, there’s definitely a book for you.
