“A taut page-turner with a strange and surprising love story at its core, Zero Repeat Forever will capture every reader who dares to pick it up.”

—Lena Coakley, bestselling author of Worlds of Ink and Shadow

He has no voice, or name, only a rank, Eighth. He doesn’t know the details of the mission, only the directives that hum in his mind.

Dart the humans. Leave them where they fall.

His job is to protect his Offside. Let her do the shooting.

Until a human kills her…

Sixteen year-old Raven is at summer camp when the terrifying armored Nahx invade, annihilating entire cities, taking control of the Earth. Isolated in the wilderness, Raven and her friends have only a fragment of instruction from the human resistance.

Shelter in place.

Which seems like good advice at first. Stay put. Await rescue. Raven doesn’t like feeling helpless but what choice does she have?

Then a Nahx kills her boyfriend.

Thrown together in a violent, unfamiliar world, Eighth and Raven should feel only hate and fear. But when Raven is injured, and Eighth deserts his unit, their survival depends on trusting each other…

Published by Simon & Schuster, USA, Canada and UK English. Also available in Spanish, Portuguese, Turkish and English Audio.

Watch this hilarious review vlog from The Inside Story.

“Teens will love the pace and dialogue.. readers will be sucked into humanity’s struggle to survive and the Nahx’s all too focused efforts to ensure that it doesn’t.” School Library Journal September 2017

“…it really is addictive and hard to put down… I didn’t want the book to end..” Teacher of YA

Takip edeceğim serilerden biri olacak The Nahx Invasions.(The Nahx Invasions will be one of the series I will follow. )” Review of the Turkish Edition at DilaraBook.

“Eighth’s character drew me in unlike a male lead has in quite some time.  His confusion was so palpable. His alien self-conflicting with human-like emotions is what made for such a strong, realistic protagonist.” Book Swoon

“Un libro que te sorprende por la profundidad que oculta y por la emotividad que desprende, con unos protagonistas diferentes a lo habitual y que te lleva a través de un viaje de sentimientos encontrados. Una preciosa historia que estoy deseando continuar….9/10.” Lectura Directa

“…a gripping novel, complete with a slow build and a gut-punch of a finale that hooks you in and doesn’t let up.” Culturefly

“The main character Raven is so complex and intricate. Prendergast has woven a true, real young teenager in the character of Raven which is this books biggest strength. She makes mistakes and gets frustrated, she’s angry and sad and in love all in one.” The Kindred Reader

“Balls to the walls badass” Write, Edit, Read, Repeat

“…there is poetry to this story, hence my comparison of this novel to an arthouse film in book form. Jarring, raw shots of scenes, each one a window into the hearts of two sentient creatures who find themselves on opposing sides of a planetary invasion.” Alexa Loves Books

“Apocalypse for the win” Reading with Rendz

“Sangre y fuego, odio y fanatismo, a cuyas llamas la autora infunde el soplo de la comprensión entre un Nahx y una humana. ¿Qué les une y cómo terminará el cruce de sus caminos? ¡Qué emocionante ha sido! (Blood and fire, hatred and fanaticism, to whose flames the author gives the breath of understanding between a Nahx and a human. What brings them together and how will the crossing of their paths end? How exciting it was!)” Review of Spanish edition in Torre de Babel

“The story is strongly driven by well thought-out characters who are not always likeable but nonetheless striking in their complexity. We are given a look at humanity that’s been peeled back a few layers due to trauma, loss, and heartbreak.” She Turns Pages

“The story is not a soppy sci fi romance…What we have is a bleak but also character driven survival tale with a very beating heart at the center.” Online Eccentric Librarian

“I am in love with this book.” Minamac Reviews

“Prendergast is a talented sci-fi writer – her world building is impeccable, her character development is complex, and her pacing is spot on.” Quill & Quire.

“There’s something eerie and complicated about this book, about the story of Eighth and Raven.” Me On Books

“HOLY. SH*T. YOU GUYS. There are not enough words to properly describe how much I LOVED this book! And the more time that passes, the more I love it. I can’t get it out of my head. I thought about it all day the following day after I finished it. I just can’t stop thinking about it! It’s really gotten under my skin in a way that not many books do.” Novel Heartbeat

“It really caught me off guard how intensely emotional it was, and how much it would affect me. The writing style was addicting in a gut-wrenching way; full of intensity and rage and sadness.” She Turns Pages
