The Battle for Earth has begun.
Doom
Victoria’s dreams of a cozy life as a small-town doctor come crashing down when the monstrous Kryptids make first contact. The alien invaders have only one goal: to turn Earth into a breeding ground. As she fights to protect her patients in their makeshift hospital, an even more fearsome alien and his beast enter the fray. She should be terrified of the male ominously named Doom. But she’s mesmerized.
As a genetically engineered war machine, Doom lives for a single purpose: eradicating the Kryptids. Coming to Earth with his brothers to save the humans should be a straightforward matter. But years of bloody battles throughout the galaxy have not prepared him for the fiery Victoria. Enchanted by the courage of that wisp of a woman, Doom offers her his protection and that of his fearless war beast, Stran, as she attempts to rescue other wounded humans. After disaster strikes their homeworld, the Xian Warriors now also face extinction.
Will the Kryptids finally defeat their only real threat, or will the delicate human that has stolen both of Doom’s hearts also be the Warriors’ seed of hope?

Character Backgrounds and Plot Summary
Victoria is a small-town doctor whose quiet life is shattered when the Kryptids invade Earth with the horrifying goal of turning the planet into a breeding ground. While other people are focused on escaping the devastation, Victoria stays behind to care for her patients in a makeshift hospital. I immediately respected her determination because she refuses to abandon vulnerable people even when her own survival is at stake.
Doom is a genetically engineered Xian warrior who has spent years fighting the Kryptids across the galaxy. He and his brothers arrive on Earth to stop the invasion, bringing their formidable combat abilities to a desperate battle for humanity’s survival. Doom might be built for destruction, but meeting Victoria brings out a different side of him. Her courage catches his attention, and he becomes determined to protect her while she continues helping the wounded.
I also really enjoyed Stran, Doom’s fierce and intelligent war beast. The bond between Stran and Doom adds another layer to the story, especially when Stran becomes part of Victoria’s protection. Their relationship develops against the backdrop of an increasingly desperate war, and the destruction of the Xians’ homeworld makes the stakes even more personal. Suddenly, they aren’t just fighting to save humanity. Their own people’s future is at risk, too.
Highlights and Limitations
The combination of alien invasion, action, and romance was what drew me into this story. The Kryptids are genuinely disturbing enemies because their plans for Earth are so much worse than simple conquest. The scenes involving Victoria trying to keep her patients alive while the world around her collapses give the invasion a human cost. I liked that she contributes through her medical skills and determination rather than simply waiting for Doom to rescue her.
Doom’s protective instincts also worked for me, particularly because he doesn’t admire Victoria for being helpless. He is drawn to her courage and her willingness to keep helping others when everything is falling apart. I enjoyed seeing this battle-hardened warrior discover that protecting someone can become just as meaningful to him as fighting an enemy. The soulmate element adds an interesting layer to the Xian mythology, too.
My biggest reservation was the pacing of the romance and the larger war. Doom and Victoria’s connection develops very quickly, and I would have preferred more time watching them get to know each other through meaningful conversations before their bond becomes so significant. I also wanted more detail about some of the major developments in the conflict. There are stretches where substantial changes happen over time jumps, and I found myself wishing I could experience more of those struggles alongside the characters instead of hearing about the results afterward.
Still, the premise has plenty going for it, and the mix of survival, alien biology, and the Xians’ unusual circumstances gives the series an intriguing foundation.
Narration
Christian Black narrates the audiobook, carrying the story through its action sequences, science-fiction elements, and romantic moments. With a protagonist like Doom, I wanted the narration to convey both the intimidating presence of a genetically engineered warrior and the softer emotions that emerge around Victoria. That contrast is important to making the romance believable.
The story also shifts between brutal battles and more intimate moments, so maintaining the difference between the danger of the invasion and the growing connection between the main characters is essential. I found the underlying story engaging enough to keep me interested in what would happen to Doom, Victoria, and the people depending on them.
Final Opinion
Doom was an entertaining start to a science-fiction romance series, particularly for readers who enjoy powerful alien warriors, courageous human heroines, fated mates, and dangerous extraterrestrial enemies. Victoria’s commitment to her patients made her easy to root for, while Doom’s transformation from a warrior focused on exterminating the Kryptids to a male with something deeply personal to protect gave the romance its appeal.
I would have liked a slower romantic buildup and more time spent showing the turning points in the war, but I appreciated the ambition of the story and the way it connects a personal love story to the survival of two species. Stran was an added bonus, and the Xian Warriors’ circumstances left me curious about the other characters and where the series will go next.
Overall, this is a solid choice for alien-romance fans who like their love stories mixed with danger, battles, and high stakes. I enjoyed the concept and the characters enough to be interested in continuing the series.
