AUTHOR AMIE KAUFMAN & JAY KRISTOFF

ILLUMINAE

 

“It certainly filled the Battlestar Galactica–shaped hole in my heart.” —Victoria Aveyard, bestselling author of The Red Queen
 
Read the New York Times bestselling blockbuster that critics are calling “out-of-this-world awesome.” The first in an epic sci-fi series unlike anything else out there.
 
Kady thought breaking up with Ezra was the worst thing she’d ever been through. That was before her planet was invaded. Now, with enemy fire raining down on them, Kady and Ezra are forced to fight their way onto one of the evacuating craft, with an enemy warship in hot pursuit.
 
But the warship could be the least of their problems. A deadly plague has broken out and is mutating, with terrifying results; the fleet’s AI, which should be protecting them, may actually be their biggest threat; and nobody in charge will say what’s really going on. As Kady plunges into a web of data hacking to get to the truth, it’s clear only one person can help her bring it all to light: Ezra.
 
Told through a fascinating dossier of hacked documents—including emails, schematics, military files, IMs, medical reports, interviews, and more—Illuminae is the first book in a heart-stopping, high-octane trilogy about lives interrupted, the price of truth, and the courage of everyday heroes.
 
“Brace yourself, because you’re about to be immersed in a mindscape that you’ll never want to leave.” —Marie Lu, author of the bestselling Legend series
 
“Prepare yourselves for Illuminae.” —EW.com
 
“You’re not in for an ordinary novel experience. . . .”  —Bustle.com
 
“A truly interactive experience. . . . A fantastically fun ride.” —MTV.com

Why this book may be a good choice for you and/or your family...

Amie Kaufman and Jay Kristoff’s Illuminae and its series are a thrilling, visually dynamic choice for readers who love fast-paced science fiction with a creative twist. Told through classified files, emails, interviews, and ship schematics, the storytelling style is immersive and unique, drawing readers into a high-stakes, interstellar conflict. The plot centers on teens Kady and Ezra as they navigate the aftermath of a space colony attack, uncovering conspiracies, AI threats, and moral dilemmas along the way. It’s a great pick for families with older teens who enjoy stories full of action, tech, resilience, and emotional depth. Content-wise, Illuminae does include some mature elements, such as strong language (censored in a stylized way), moments of violence, and light romantic/sexual references between characters, though these are not explicit. The romantic content is brief and appropriate for older teens, focusing more on emotional connection than physicality. Because of the book’s inventive structure and thought-provoking themes, it’s a great way to engage reluctant readers or spark deeper discussions about technology, ethics, and human connection in extreme situations.

AUTHOR NANCY KRESS
 
STEAL ACROSS THE SKY (BOOK 1)

Aliens try to atone for past wrongs to humanity and take twenty-one humans on a revelatory journey in this science fiction novel by a Nebula Award–winning author.

The aliens appeared one day, built a base on the moon, and put an ad on the internet:

“We are an alien race you may call the Atoners. Ten thousand years ago we wronged humanity profoundly. We cannot undo what has been done, but we wish humanity to understand it. Therefore, we request twenty-one volunteers to visit seven planets to Witness for us. We will convey each volunteer there and back in complete safety. Volunteers must speak English. Send requests for electronic applications to witness@Atoners.com.”

At first, everyone thought it was a joke. But it wasn’t.

This is the story of three of those volunteers, and what they found on Kular A and Kular B . . .


Praise for Steal Across the Sky

“Kress skillfully explores the consequences of her ideas. . . . Arrestingly ambiguous and persuasively set forth—in the best science-fiction tradition, guaranteed provocative no matter what your personal opinions.” —Kirkus Reviews (starred review)

Why this book may be a good choice for you and/or your family...

Steal Across the Sky is a thoughtful, character-driven science fiction that delves into big ideas about life, death, and morality, making it appealing for families who appreciate introspective and philosophical storytelling. The novel features moderate sci‑fi violence—such as tense confrontations and depictions of prisoners—but it is not excessively graphic. There is minimal swearing and no explicit sexual content or romance, so the focus remains on plot and ideas rather than mature themes. For readers who enjoy space‑based adventures that provoke discussion without heavy sensual or profanity‑laden scenes, this book can be an engaging choice. On the other hand, this story’s slower pace and emphasis on existential questions may not suit families looking for fast‑paced action or light entertainment. The violence, while not graphic, can be unsettling—characters endure capture, deprivation, and the threat of death, which could be intense for more sensitive readers. Additionally, the lack of clear romantic plotlines and the novel’s introspective tone might feel dry to those seeking emotional drama or straightforward thrills. In short, Steal Across the Sky works best for readers comfortable with thoughtful, sometimes somber science fiction rather than casual, action‑heavy fare.

AUTHOR MADELINE L'ENGLE

A WRINKLE IN TIME

 

This is Book 1 of the Time Quintet Series

It was a dark and stormy night; Meg Murry, her small brother Charles Wallace, and her mother had come down to the kitchen for a midnight snack when they were upset by the arrival of a most disturbing stranger.

 

"Wild nights are my glory," the unearthly stranger told them. "I just got caught in a downdraft and blown off course. Let me sit down for a moment, and then I'll be on my way. Speaking of ways, by the way, there is such a thing as a tesseract."

 

A tesseract (in case the reader doesn't know) is a wrinkle in time. To tell more would rob the reader of the enjoyment of Miss L'Engle's unusual book. A Wrinkle in Time, winner of the Newbery Medal in 1963, is the story of the adventures in space and time of Meg, Charles Wallace, and Calvin O'Keefe (athlete, student, and one of the most popular boys in high school). They are in search of Meg's father, a scientist who disappeared while engaged in secret work for the government on the tesseract problem.

 

A Wrinkle in Time is the winner of the 1963 Newbery Medal.

AUTHOR WENDY KNIGHT

 

BEFORE THESE WINGS
 

Phoenyx and Cole survived the end of the world. The alien invasion that took out most of the population and crippled any form of government—they’d fought that, and they’d survived.


Or at least, they’re trying to.
 

They battle starvation, fear, exhaustion, and death every single day, and while the future doesn’t look bright, at least they’re fighting for it.
Hope is hard to come by, but when they need it most, it does come—in the form of a different alien entirely—beautiful, with the wings of a fairy, the voice of a siren...
And the teeth of a vampire.

 

Sometimes hope is most devastating of all.
 

Never Trust Beautiful Things.

AUTHOR BRANDON Q. MORRIS
 
THE DEATH OF THE UNIVERSE (BOOK 1)

For many billions of years, humans—having conquered the curse of aging—spread throughout the entire Milky Way. They are able to live all their dreams, but to their great disappointment, no other intelligent species has ever been encountered. Now, humanity itself is on the brink of extinction because the universe is dying a protracted yet inevitable death. They have only one hope: The ‘Rescue Project’ was designed to feed the black hole in the center of the galaxy until it becomes a quasar, delivering much-needed energy to humankind during its last breaths. But then something happens that no one ever expected—and humanity is forced to look at itself and its existence in an entirely new way.

Hard Science Fiction.

Why this book may be a good choice for you and/or your family...

The Death of the Universe by Brandon Q. Morris is a hard science fiction novel that delves into humanity's struggle for survival as the universe approaches its end. The narrative is rich in scientific concepts, focusing on themes like cosmic entropy, artificial intelligence, and the ethics of survival. For readers who appreciate intellectually stimulating content without the distractions of explicit romance or gratuitous violence, this book offers a compelling exploration of existential questions and scientific possibilities. The absence of explicit sexual content and minimal use of strong language make it a suitable choice for readers who prefer content that is thought-provoking yet not graphic. However, the book's emphasis on complex scientific theories and its dense narrative structure may not appeal to all readers. The lack of traditional action sequences or emotional character development could make it less engaging for those who prefer more dynamic storytelling. Additionally, the minimal presence of interpersonal relationships and the focus on abstract concepts might not resonate with readers seeking character-driven narratives or emotional depth. Families or readers looking for more traditional science fiction adventures with clear-cut heroes and villains might find this novel's approach more challenging to connect with.
