I reviewed Hive, Book 1 of this series here. I couldn’t wait to continue the story of Diego, Isabel and find out what happens when Diego time jumps. Finally, here is my review of Book 2.

Blurb

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.

Isabelle 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.

Review

Jump carries on from where Hive left off…Diego has jumped back in time…and meets himself, or at least another version of himself…then another.

Whilst trying to save the world, and the love of his life, it seems Diego and his other selves from other timelines time travel to try to get messages to their former self and his friends to try to change the outcome of their timeline, because in each one, the world ends.

Separated and unsure if the other is even alive, Diego and Isabelle have to negotiate their way out of trouble to try to work out what might happen and how they can stop Dave Kirkland, tech bro narcissist and billionaire, from taking over the planet, killing most of the population and ending the world.

The world building over the two books is superb, from the domes to the dystopian landscape outside them.

As with Hive, the pace is fast, but nothing is skipped and the characters are well crafted and believable. With chapters told from different perspectives, we get a deep understanding of both Diego and Isabelle, their hope and despair for themselves, each other and the world. The other chapters detailing their friends are interspersed, bringing the story together perfectly.

I am fascinated by the concept of time travel and the butterfly effect. There is plenty of that here, with past and future actions affecting timelines. The group has to work hard to remember to send messages back and forth, so as not to create paradoxes.

D.L. Orton creates a tension between hope and despair, taking the reader on a roller coaster of emotions.

I am again really looking forward to the next book in the series, Dome. What a place to end this part…

Thanks to the author and @The_WriteReads for a copy of the book to read and review for this blog tour. Please look out for other reviews over the coming week.
