Extinction Threshold

De: R.D. Brady

Narrado por: Amelia Hugh

A virus released from the permafrost leaves humanity’s survival on a razor’s edge–and Hannah Aldeen’s family in the crosshairs of an unrelenting threat.

Humanity is on the brink of extinction. Half of the population has already perished, and the remaining survivors are divided into two groups–the immune and the Ragers.

Hannah Aldeen thought she had it figured out. Living in her fortress-like home in upstate New York, she’d prepared for the worst that climate change could throw at her. But nothing could have prepared her for the terrifying reality of a global pandemic.

Now with the Omega Corporation hot on her heels, Hannah must fight to keep her family safe from the clutches of a ruthless enemy. She doesn't know why they're after her, but she knows that she will stop at nothing to protect those she loves.

As the clock ticks down and the threat of annihilation looms large, Hannah must make impossible choices and take extreme measures. She'll have to push herself to the limit and beyond, facing danger at every turn in a race against time to save the only thing that matters–her family.

With heart-stopping action and pulse-pounding suspense, Extinction Threshold is a gripping tale of survival in a world gone mad. Hannah's story will leave you on the edge of your seat, breathless with anticipation until the very last seconds.

global warming releases next pandemic virus

I thoroughly enjoyed this take on a zombie virus released from the permafrost as a result of global warming. Very relatable characters from scientists to journalists to fabulous.

Wow

Wow what a good read I enjoyed the book and the audiobook. If it wasn't for our book club I would have finished the book the same day I started. What I liked was that there was lots of action as well as moments where I wanted to cry. This book isn't all action and no hart. The found family aspect of the book I also like. And then we have the narration so good, I can't wait to listen to more book she narrates.

I hate zombies

I hate zombies, zombie movies, etc. they are boring and unrealistic. BUT, this story makes it real, makes it fearsome. The narrator KILLED this story pun intended😂 She made it so entertaining and the book itself was well detailed and fun! Glad I gave it a listen!!❤️

Please send more!

Usually I wait until a series is a few books in before I buy. But I didn’t see any other ones I was interested in. So I got this book. And I loved it. Everything zombie fan would like. And very heartwarming. It’s a book about grown-ups for grown-ups. I’m not a writer, so it’s hard for me to explain. I just know I didn’t feel like a teenager with writing the book or the book was written for a teenager ha. Anyway, please write more soon. Please!

Unexpectedly Hooked from the First Chapter

I’ll admit, Extinction Threshold isn’t my usual genre, but it was our book club pick—and I ended up really enjoying it. The story hooked me right away with its fast pace, high tension, and sense of urgency that kept me wanting to know what would happen next. It’s filled with action, mystery, and just the right touch of emotion to make you care about what’s at stake. What truly elevated the experience for me, though, was the audiobook. Amelia Hugh did an outstanding job narrating—her delivery captured every ounce of suspense and personality, pulling me straight into the world of the story. Her voice work made the danger feel real, the characters believable, and the quieter moments surprisingly moving. Even though sci-fi thrillers aren’t usually my go-to, this one was a ride worth taking—and the narration made it unforgettable.
