Hive (Madders of Time Book 1) - DL Orton

'In a crumbling biodome, surrounded by endless seas and swarms of microdrones, humanity's last survivors cling to hope.

For Isabel, a dying scientist, and Diego, the man she loves, time is running out—literally. The Earth is ravaged, and the biodome that was meant to save humanity is failing. But when Isabel stumbles upon a long-lost time bridge, the possibility of changing the past emerges, offering one final chance to rewrite history.

There's just one problem: only one person can make the jump.

As they grapple with the weight of impossible choices, love, and regret, Isabel and Diego must decide whether altering the course of time is worth the risk. Will their sacrifice save the future, or will tampering with the past ensure humanity's extinction?'

 Hive is a story of the last people on Earth and second chances and asks the question, if you could change the past to heal the future would you? Could you? I liked the ideas behind Hive a lot and, happily, it did not let me down.

From the get-go, in a broken biodome under attack by nature and science to the past, where we get to see our protagonists lives and how they are heading to 'now' the connection between Isabel and Diego is strong and made me really root for them to get everything right. The 'now' is a bleak time and the author makes that seem believable but the 'then' feels like 'hope' so there is a good mix to keep the reading fresh.

I did not know that this series is linked to another by the same author until I had started reading and saw posts from other reviewers so I will be going back to them soon while waiting for Madders of Time 2.
