Sasha is a woman living as a man to infiltrate the Russian military, driven by a single purpose: revenge for the massacre of her family. Her disguise holds until her path crosses Kirill's, her superior, a captain of magnetic charm and flawless exterior who will be the one to introduce her to true carnage. They could not be more opposite, yet they collide under the strangest circumstances, and the pull between them threatens everything she has hidden. Behind Kirill's perfection lurks a manipulative, emotionless monster with his own dark family history and ambitions to rule, and he is as much Bratva as soldier. As Sasha edges closer to the truth about who destroyed her family, she risks Kirill uncovering her secrets, including why she is pretending to be a man, and luring her past the point of no return. With a gender-disguise premise often compared to Mulan, this opener blends military intrigue, mafia power struggles, and a slow, dangerous attraction. It is the first installment of a trilogy and ends on a cliffhanger; it is explicit and built on forbidden, antagonistic chemistry.
