The multiverse is collapsing. The time machine is broken. And humanity’s last hope? Might already be dead.

Seven months after the EMPs brought the world to its knees, a handful of scientists are racing against extinction—and each other. Somewhere in a flooded skyscraper lies a wormhole generator that might be able to undo the apocalypse. If they can find it. If it still works. If it doesn’t kill them first.

Meanwhile, Diego Nadales wakes in a cell, his face bloodied and his memories fractured. He's being accused of terrorism, treason, and time travel. The last one, at least, is true.

Isabel is trapped inside a biodome ruled by the man she once trusted. But her bees—microscopic drones designed to save the planet—have been hijacked and weaponized. If she doesn’t find a way out soon, her creation will wipe out the last threads of life on Earth.

Old friends return. New enemies rise. And somewhere in the chaos, one small spark of hope just might be enough to ignite a revolution.

The clock isn’t ticking. It’s blowing up.

JUMP is the perfect sequel to HIVE, the first in Orton’s Madders of Time series.
Readers are thrust back into the action with our leads Diego & Isabel, each trapped in perilous conditions after the events of the first book, facing their own worst nightmares. It’s the raw, human aspect of Orton’s writing that endears the reader to these characters and their own going plights. She delivers dark, emotional stories with just a sliver of hope to keep the reader ensconced in the narrative.
Although the stakes are high, the book is not without its humour which strikes the perfect balance, relieving some of the continuous pressure set by the pacing throughout.
JUMP is a wonderful expansion of this sci-fi universe and will leave readers desperate for more.

A Breathtaking Sci-Fi Adventure Novel

JUMP: MADDERS OF TIME BOOK 2 by D. L. Orton is a compelling and entertaining science fiction novel. As the second installment in the Madders of Time series, readers will enjoy it more if they read Book 1 first. The author’s creativity shines through, especially in world-building and storytelling.

The plot thickens as Kirkland has both Isabel and Diego separated and under his control, manipulating them to do his bidding while they cling to their love and hope of saving each other. Meanwhile, the worsening "drought crisis" — caused by a sharp decline in the bee population — is exploited by Kirkland, who pretends to offer solutions but actually aims to turn the bots into deadly machines for his greed.

This edition offers a more immersive and suspenseful experience, leaving readers eager to see if Isabel and Diego will reunite, save each other, resolve the crisis, and save humanity. In this edition, action scenes are more frequent, adding excitement for fans of intense storytelling.

The author employs multiple narrative voices, improving the story's flow and making it easier to understand and follow. Events are seamlessly connected, maintaining clarity and purpose throughout. Each chapter begins with a photo ID and an introduction or "target," helping readers identify the current narrator.

The book is well-written, professionally edited, and free of grammatical errors. Scenes are thoughtfully crafted and vividly detailed, allowing readers to visualize the events as if watching a film. Fans of time-travel sci-fi will find this book engaging.

Jump is a wild, inventive, and adrenaline-charged ride through a collapsing multiverse where hope feels as fragile as time itself. DL Orton expertly weaves together Diego’s fractured memories, Isabel’s desperate fight inside a dangerous biodome, and a race to recover a wormhole device that could rewrite humanity’s fate. The stakes are sky-high, the twists relentless, and the science wonderfully imaginative. While the story occasionally overwhelms with its many moving parts, the emotional core, friendship, survival, and sacrifice keeps it grounded. Bold, tense, and packed with action, Jump is a thrilling installment that pushes its characters, and its readers, to the edge.

If Hive was the spark that lit D.L. Orton’s dystopian, time-tangled universe, Jump is the wildfire that follows—hotter, messier, and impossible to look away from. The second installment throws you straight into the chaos without a safety net, expanding the world in ways that are bolder, darker, and more emotionally charged.

Where Hive built its tension on impending collapse, Jump plunges us into the aftermath. The multiverse is crumpling in on itself, the timelines are misfiring, and humanity’s last shot at salvation lies buried in a half-drowned skyscraper—if it hasn’t already imploded. It’s the kind of high-concept premise that could easily spiral into confusion, but Orton roots it in the raw, beating hearts of her characters.

Diego’s storyline hits like a punch to the gut. He wakes up battered, accused of crimes he may or may not have committed, and forced to piece together both his memory and the remnants of a world gone sideways. His chapters thrum with claustrophobic urgency—every revelation tilts the timeline a degree off-center, and you feel the ground shifting with him.

Isabel’s arc is just as tense but cuts deeper emotionally. Trapped in a biodome run by someone she once trusted, she has to confront the nightmare her innovations have become. Her bees—those tiny, brilliant creations meant to heal the planet—have been twisted into instruments of annihilation. Isabel’s quiet resilience, rage, and grit give the book its emotional spine, especially as she navigates a world where hope is a far thinner resource than air.

And then there’s Madders. The AI is back—acerbic, earnest, infuriatingly logical—and his logs continue to be some of the smartest, funniest, and most poignant moments in the book. Old allies return, new threats emerge, and the ensemble expands in a way that makes the world feel both larger and more claustrophobic at the same time.

Orton maintains her signature blend of scientific imagination and character-driven storytelling, but Jump feels sharper and more kinetic than its predecessor. The pacing rarely lets up—twist after twist ricochets through the narrative, and the stakes aren’t just high, they’re multiversal. Yet, despite the scale, the story never loses sight of the small, human moments: a shared look, a broken memory, a stubborn flicker of hope.

If there’s a challenge to the reading experience, it’s the sheer density of everything happening at once. The collapsed timelines, fractured realities, and interconnected plotlines demand attention. But for readers who love immersive sci-fi that trusts them to keep up, this complexity is part of the thrill.

By the end, Jump leaves you breathless, a little devastated, and desperate for Dome, the next chapter in this unraveling tapestry of love, loss, and quantum catastrophe. It’s a sequel that not only lives up to Hive, but fearlessly broadens the horizon—proving once again that Orton is at her best when she’s balancing big ideas with bigger feelings.

Smart, suspenseful, and deeply human, Jump cements the Madders of Time series as a standout in time-travel fiction. If Hive hooked you, Jump will leave claw marks.

Jump catapults readers back into a collapsing multiverse where time travel, fractured loyalties, and the threads of human survival collide with explosive urgency. Seven months after the EMPs destroyed modern civilization, a scattered group of scientists races to locate a wormhole generator submerged in the ruins of a drowned skyscraper—one last chance to undo the apocalypse, assuming it hasn’t failed or turned lethal. Elsewhere, Diego Nadales awakens in a cell, battered and accused of treason, terrorism, and, inconveniently, time travel. Isabel, meanwhile, is trapped inside a biodome ruled by a man she once trusted, her brilliant technological “bees” twisted into weapons capable of erasing the last signs of life on Earth. As old friends reappear and new enemies emerge, the smallest spark of hope could be enough to ignite a revolution, if anyone survives long enough to strike the match.

Having read the first book in the series, it was deeply satisfying to step back into Isabel and Diego’s lives. Their world, broken, dark, and dangerous, remains anchored by characters who feel real, flawed, and often unexpectedly funny in ways that ground the story amid its high-concept stakes. The new characters blend seamlessly into the narrative, expanding the universe without overwhelming it. The science fiction elements are especially noteworthy; they feel believable and carefully constructed, never drifting into the kind of far-fetched territory that pulls a reader out of the moment. Instead, the scientific tension enhances the emotional weight of the story.

Orton strikes a balance between gripping action, sharp humor, and aching humanity, delivering a sequel that not only raises the stakes but deepens the connection to the characters at its core. Jump is an exhilarating continuation of a series that knows how to blend science, heart, and chaos into something genuinely compelling.

DL Orton opens Jump: Madders of Time with riots and upheaval, and he keeps the journey high-stakes up until the final page.

Jump: Madders of Time is a blood-pounding journey. Set just after the events of the first book Hive, Orton ups the stakes, with the multiverse collapsing and the Biodome, previously humanity’s last sanctuary, in danger of being destroyed.

Orton managed to up the stakes on this novel- which is impressive considering the last one was so fun. I would recommend this book to fans of sci-fi and a good adventure!

Jump: Madders of Time Book 2 is a riveting time travel novel. It features two lovers and scientists, Isabel and Diego, who are racing to go back in time and rewrite the fate of a crumbling humanity. Jump is a fast-paced, time-bending novel set across multiple climes and times, but the action never lets up.

DL Orton's worldbuilding stands out throughout the novel. He delivered a chaotic and mesmerising world, collapsing on itself from past mistakes, and I was there all for it!

Explosive, fast-paced and intense, Jump takes us to a universe that's on the verge of collapse. While Isabel struggles to preserve the last biodomes keeping humanity safe, Diego, accused of time-travel (which is now a crime) must recover a wormhole device that could rewrite humanity’s fate. Jump is a wild ride set in a post-apocalyptic universe, perfect for sci-fi and adventure fans.

I enjoyed Jump: Madders of Time. It was set in a post-apocalyptic world, where only a few humans remain, and a band of scientists needed to work together to steal a time machine which could help them undo the wrongs that got thjem to this place. New alliances were formed with old enemies, and there was enough action to go around. This was a fun read that sci-fi fans would love.

Jump continues D.L. Orton’s fabulous storytelling from Hive, the first book in the Madders of Time series. Right from the prologue, I was completely pulled back into Isabel and Diego’s crazy, beautiful, time-twisting world. Madders’ chronicle of what’s going on in the world is as enlightening as ever, and the rest of the gang is back—making the best of it—along with some great new characters.

The science-fiction side feels believable, but it’s the characters that make it special—funny, flawed, and so real you can’t help caring about them. The story moves fast, full of twists and “oh no!” moments that kept me reading way too late. The way Orton weaves the story is just masterful.

Jump: Madders of Time – Book 2 by D. L. Orton’s continues the series with even more excitement and heart. This is the second book and what stands out is that the sci-fi elements feel believable and well-thought-out, and so are the characters. They’re funny, imperfect, and so real that you immediately care about what happens to them.

This book is a fast, imaginative, and thrill-packed dive through a chaotic multiverse. D. L. Orton’s creativity shows clearly in the world-building and storytelling, making this a highly engaging and entertaining read.
