• My review

  WHAT. A. GOOD. BOOK. Period.

  Sigma delivers everything I loved about Alpha—with one major difference: the mystery is gone. And honestly? I loved that too.

  Where Alpha kept things deliberately vague, Sigma pulls back the curtain completely. We’re told exactly where the super-soldiers come from, how the experiment works, and what was really happening behind the scenes during the events of Alpha. Reading this felt like seeing the same story from the opposite side of the chessboard—and it was so satisfying.

  This book overlaps heavily with Alpha, covering many of the same events, but from Sigma’s perspective. And that’s what makes it such a fun, rewarding read. If Alpha was about the heroine navigating the unknown, Sigma is about understanding the system, the science, and the brutal reality of the super-soldier program.

  That said: you need to have read Alpha first. This book assumes you already know and care about that world. And to truly love this one, you also need to be okay with the mystery being fully revealed.

  The romance unfolds alongside nonstop external threats: a psychotic ex, enemies from Shiloh’s past, internal betrayals, and a genuinely unhinged scientist pulling strings.

  If Alpha made you curious, Sigma gives you answers.

  Warning: some injuries and deaths are very very graphic, be careful if you are sensitive to these topics.

  The Heroine: Shiloh

  Shiloh is a fantastic FMC.

  She’s skeptical about love (for very good reasons), mentally tough, resilient, and genuinely smart. Not “strong because the author says so,” but strong in the quiet, believable way—she survives, adapts, and doesn’t trust easily.

  It was refreshing to read a heroine who doesn’t romanticize her trauma or instantly fall into blind devotion. She questions everything, including her own decisions, and that made her feel incredibly grounded.

  The Hero: Sigma

  Sigma is intriguing mostly because of his role within the super-soldier hierarchy and his insight into the experiment itself. Through him, we finally understand the soldiers’ internal dynamics.

  As a romance hero, he hits familiar beats: protective, super strong, intelligent, territorial, and jealous. He’s solid, dependable, and very much an alpha-type presence—but his real strength is the perspective he offers rather than reinventing the archetype.
