In Olympus Dawn by Zoë Routh, Dr. Victoria Tang develops a cartridge capable of converting carbon dioxide into breathable oxygen, positioning Mars for rapid habitation and placing her at the center of a corporate power struggle. When she is seized by agents acting for Lincoln Ellison, rival executive Aryanna Sharif launches the Nyx Odyssey under Commander Troy Bruin to prevent a unilateral claim over the planet. As Nyx travels toward Mars, evidence emerges that Ellison has embedded corrupted guidance code within their flight systems, forcing Deputy Commander Xanthe Waters to assume neural control during the descent. Both expeditions converge near a prebuilt habitat at Kunlun while the control of atmospheric technology, legal authority under the Mars Accord, and the future governance of Mars hang in balance as the settlement begins under uncertain terms.

Zoë Routh’s Olympus Dawn is an ambitious science fiction novel, with the title digging into a new epoch on Olympus Moonbase. Routh puts her timeline in a near future that is fully and intelligently realized, with technology like torpor rotation and adaptive ship A.I. systems functioning as integrated infrastructure. Troy is a protagonist who is a true action-under-crisis guy, but it's Xanthe that I like most. The strategic oversight and negotiation skills are on point, all while juggling the sabotage inside Kunlun’s life support systems. Ellison is a worthy antagonist with a knack for calculated manipulation and malicious airlock decompression. Routh’s skill as a writer is cemented in the landscapes, where dust storms shear across the horizon. It is so immersive and so gorgeous. Overall, this is the perfect read for science fiction lovers who enjoy solid environmental engineering, power politics, and planetary settlements molded by shared human and machine stewardship. Very highly recommended.

Olympus Dawn is the fourth book in the Gaia series by Zoë Routh. Life on Earth is chaos as political tension rises and human life becomes another commodity. CEO Lincoln Ellison of Spaceward Bound has set his sights on Mars and wants to make it his personal empire. He has big plans with a revolutionary terraforming technology and wants to stake a claim on the red planet. On the other hand, Commander Troy Bruin and Deputy Commander Xanthe Waters were struggling to keep their crew together as they battled against the harsh environment and sabotage. Each decision made has a consequence, and everyone will pay the price for it. It is up to Troy and Xanthe to stop Lincoln Ellison from destroying Mars and the human race before it is too late.

Author Zoë Routh wrote a fantastic story with enough tension, action, and thrills to keep me hooked. I loved the descriptions, the action, and the political tension. Usually, I don’t enjoy stories with political themes, but this one is different. I enjoyed it more than I thought I would. This character-driven story has plenty of twists and turns to keep you entertained for hours. While the protagonists are exciting, Lincoln truly surprised me. He is the perfect antagonist who makes the story interesting and much more real. I found Xanthe’s sense of responsibility and struggles with leadership to be relatable. Considering the current situation in the world, I can understand how a power-hungry CEO tries to profit from every situation. The narrative style and the pace of the story were perfect. I was fully immersed and engaged. I cannot recommend Olympus Dawn highly enough!

Olympus Dawn is the fourth book in the Gaia series by Zoë Routh, and a wonderfully crafted story for science fiction fans. The near future is ugly for humanity, with the Earth ravaged by ecological collapse. Lincoln Ellison is a ruthless corporate tycoon whose eyes are set on Mars, and he will stop at nothing to colonize it and make it his own. He starts by engineering the kidnapping of Dr. Victoria Tang in an effort to steal her revolutionary air-scrubbing technology. Gaia Enterprises must accelerate its Mars expedition to prevent Ellison from claiming the Chinese-built Kunlun base and monopolizing humanity's future. Meanwhile, Commander Troy Bruin leads a crew of six on the Nyx Odyssey, a nine-month mission that is fraught with danger and sabotage attempts. The dangerous landing on Mars is just the start of their troubles, and Ellison’s treachery haunts them. They must partner with a sentient A.I. to establish Vesta. Can they beat Ellison, who has proven thus far to be unstoppable?

Zoë Routh delivers an imaginative tale that is chilling in its exploration of human greed and presents larger-than-life characters, especially Troy, who must transition from a celebrity astronaut to a humble leader in very challenging times. Questions about humanity’s future and whether we deserve a secondary home are central in this enthralling story. The setting is fantastic, and from the clamor of the refugee camp to Mars’ ochre desolation, the author offers imagery that compels you to think about the characters' fates. Olympus Dawn left me with one important message: our survival depends on how much we are willing to sacrifice as individuals for the welfare of everyone, and that even broken people can still build something in a broken world.

Author Zoë Routh brings yet another enthralling installment of the Gaia Enterprises series with book 4, Olympus Dawn. Dr. Victoria Tang has found a way to terraform Mars, and Spaceward Bound CEO Lincoln Ellison is quick to capitalize on her discovery. He schemes to have her kidnapped and sends Captain Gareth Barrio and his Pinnacle crew to expand his empire on Mars. Meanwhile, Aryanna Sharif and Maja Garcia choose Dr. Troy Bruin to lead the crew of Nyx Odyssey to Mars and colonize the planet. Troy's second-in-command, Xanthe Waters, reluctantly joins the mission. However, her ThinkLink updates continue to cause Xanthe trouble. Meanwhile, Ellison resorts to corporate sabotage and incites riots at Po Secco. Can Troy, Xanthe, and their allies stop Ellison's ruthless takeover and complete their mission?

Zoë Routh expands the epic saga of the Gaia Enterprises series to Mars with a page-turner of a tale in Olympus Dawn. Political intrigue, action, and drama seep through the pages of this book. Anyone who loves well-written space adventure stories will have a blast with this novel. The plot flows smoothly, and when you realize the scale of the story, it's all the more impressive. You won't want to put the book down before finishing it. One of my favorite aspects of this series is how it features various factions with their own agency. This leads to a lot of friction, with allies and enemies constantly changing sides. The characters are fleshed out well with their own backstories. Troy, Xanthe, Madison, and Volkov were my favorites. Fans of books such as The Expanse will love this series.

Olympus Dawn is the fourth book in the Gaia series by Zoë Routh. In this thought-provoking work, the author skillfully demonstrates that the greed of the rich and the powerful knows no limits. In a time when humanity faces many crises, a ruthless CEO, Lincoln Ellison, sets his sights on Mars and decides to make it his. He will do anything possible to achieve this goal, including taking control of a revolutionary terraforming technology by any means. But the battle-tested commanders and their motley crew are determined to stop him. Commander Troy Bruin and Deputy Commander Xanthe Waters have one mission: keep their crew alive. But they face sabotage and enemies from the past and must unravel the truth quickly before Ellison’s greed destroys humanity.

Zoë Routh has crafted a tale that is fast-paced and filled with tension. The setting is vividly drawn, a near future when the Earth’s atmosphere is poisoned by pollution. Dr. Victoria Tang’s technology, which is capable of cleaning the air and terraforming Mars, introduces the premise in a way I never expected. Her kidnapping creates the initial crisis, and from then on, the tension builds through every page. Olympus Dawn's characters had me hating the villain, like billionaire Lincoln Ellison, and rooting for the heroes like Commander Troy Bruin and Deputy Xanthe Waters. The conflict is expertly handled, and I loved how the author uses the time factor to create a sense of urgency. This action-packed novel gave me all the elements I enjoy in well-crafted science fiction thrillers. It is a book that is hard to put down.
