A lot or a little?

The parents' guide to what's in this book.

Educational Value

Set mostly in Europe, Undying offers descriptions of Prague and Catalonia in the future. The book might be spur a discussion of what it means to be human.

Positive Messages

Humanity is resilient and can often find solutions monumental problems. Individuals can play an integral part in shaping the future.

Positive Role Models & Representations

Mia is a thief, but she's driven to crime in order to protect her younger sister. She's impulsive and stubborn, but she's also clever and resourceful. Jules is highly academically gifted and is much more cautious, yet he's able to think under intense pressure.


Violence is threatened but rarely executed. Aliens invade Earth and start a plague that kills hundreds. A major character is shot.  


Mia and Jules fall in love over the course of the book. They are mildly flirtatious, embracing passionately a few memorable times.


In general, the characters avoid cursing, but they use "s--t" and "goddamn" one or two times.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that Undying is the second half of the science-fiction adventure begun in Unearthed, from the writing team of Amie Kaufman and Meagan Spooner. Main characters Mia and Jules work to stop and fight an alien invasion, but since they've crashlanded in Europe, they're working on it from there, not outerspace.

What's the story?

Picking up where the first volume left off, UNDYING continues the adventures of Mia and Jules as they frantically try to stop an alien invasion of Earth. Having uncovered the secrets of a giant spacecraft, they stowaway on a shuttle bound for their home planet, accompanied by two of the Undying, Dex and Atlanta. They crashland in Europe and are taken into custody by agents of the International Alliance. No one believes Mia and Jules, though, insisting the invasion to be a hoax. Jules and Mia must escape and find absolute proof that Earth is about to be taken over by hostile extraterrestrials.

Is it any good?

Moving from the marvelous to the mundane can be jarring, and this mostly earthbound follow-up to a high-flying adventure in space may slightly disappoint faithful readers. Authors Amie Kaufman and Meagan Spooner make their lead characters Jules and Mia as adorable as ever, but running around Europe isn't quite as interesting as exploring an ancient, puzzle-filled, alien spacecraft. There's still plenty of crisp, quirky dialogue, and the action never flags, which may be enough for readers seeking a new spin on alien invasions.

Talk to your kids about ...

  • Families can talk about how Undying offers a new take on the familiar trope of alien invasion. How might humanity react if it discovered that it is not alone in the universe?

  • How has climate change affected the natural world? What can be done to curb the destruction that's happening? How does the media address the situation?

  • Mia and Jules have very different personalities, but they're romantically attracted to each other. What do you think works best,  being with someone who's like you or different from you?
