When beast master Dominik Ralston agrees to pose as Sienna Heathwood’s husband for a government assignment, he anticipates the pretense and even the deceit. What he doesn’t expect is the fierce desire she awakens within him, or the struggle to keep the need to claim her from clouding his judgment. Disguised as a scientific expedition to New Columbia, their true mission is to uncover whether the nation is secretly mining iron and supplying it to an emerging superpower that treats its people as mere commodities.
As Dominik and his hawk navigate the treacherous wilds of an unexplored region, he begins to suspect Sienna’s genetic talent is far greater than anyone, including Sienna herself, could imagine. Dominik has to acknowledge a startling and unwelcome fact: their own government may have been exploiting her for years. But revealing the truth could shatter her fragile world, for Sienna has already sacrificed her freedom, her trust, and even her very heart, in service to her nation. She has endured marriage after marriage to men chosen not for love, but for their country to maintain control over her.
The one thing Sienna can’t deny is the fire Dominik alone has been able to ignite within her. For the first time, Sienna experiences true passion at Dominik’s hands. And as they get closer to discovering the truth of New Columbia’s deceit, Sienna might have to decide if a life with Dominik is worth risking the future of the ranked guardian position that has always defined her.
Captivated by Dominik by Sarah Westill is absolutely fantastic. She nails the perfect combination of dystopia, romance, and suspense.
In New Columbia, our couple must face treachery, lies, and even death. But will Dominik and Sienna find love and happiness?
Sienna Heathwood
Sienna hasn’t been given much hope or much of a say in her lifetime. She has an extremely rare gen-heir ability, which others have controlled since she was old enough to use it. Yet, she really doesn’t know how to control this power completely. Like any gift in life, she needs to practice to figure it out. However, there isn’t any time for that, as she is constantly working and takes little time for herself. As a team leader, she is continually working to strengthen government trade agreements.
I like Sienna’s character, strength, and the way she can take charge, especially in a crisis.
Dominik Ralston
Dominik is a beastmaster, like his father. Yet Dominik’s beast is a hawk, not a wolf. His hawk has a fun personality and helps push Dominik and Sienna together. He also guides Sienna against using her power on Dominik. Dominik is a laid-back kind of guy, but he takes his work and hawk seriously. He is head over heels for Sienna, but she needs to heal and learn to trust first. Dominik doesn’t push her, but he does keep her on her toes.
He comes from the famous Ralston family line. There are lots of Ralstons in the previous books, and it is fun to see them interacting like a family. I like Dominik as a character and adore how he helps Sienna see the light.
Five Stars
My rating for Captivated by Dominik by Sarah Westill is five stars. I really enjoyed being back in the Gen Heirs world. If you haven’t stepped into this amazing post-apocalyptic world, I highly recommend it. Sarah Westill’s writing style is phenomenal. It does get a bit steamy, but I am sure you can handle it. 😉
