Genre: Thriller, Romantic Suspense
**NEW RELEASE on Feb 10, 2026! PreOrder Now!**
The Serpent’s Order is the fourth installment in The Serpent’s Series by S.Z. Estavillo and serves as another fantastic addition to the collection. As soon as I started reading, I was captivated and couldn’t have set it down even if I wanted to. It kicked off with an explosive start and maintained that momentum from the very first page to the closing one.
The Serpent’s Order is a dark and intricate read filled with enough action to keep those pages turning. The world-building was masterfully crafted, making it easy to visualize everything unfolding in my mind as if I were watching a film.
The Serpent’s Order tells the story of two women on opposite sides of the law working on the same case. Von Schlange, also known as The Serpent Woman, returns once again but this time finds herself employed by a clandestine group dedicated to taking down the villains. Von is not particularly excited about this new role, but she didn’t have much choice in the situation.
Von is on a mission to eliminate corrupt police officers while trying to navigate her new job. She also finds herself partnered with Xander Holt, a former Navy SEAL. Together, Von and Xander develop a strong working relationship as a slow-burn romance begins to simmer between them.
Detective Anaya Nazario is on a quest to identify corrupt officers within the system while also trying to rid the streets of Los Angeles of a synthetic “zombie drug,” which is more lethal than fentanyl and resistant to Narcan. Nazario’s pursuit of the dirty cops makes her a target.
I relished every single story in The Serpent’s Series and can’t choose a favorite because I enjoyed them all. I appreciate the plot chosen for The Serpent’s Series, featuring two women on opposing sides of the law, essentially working towards the same goal. I would be thrilled to read more tales in this universe with Von and Nazario.
I wholeheartedly recommend The Serpent’s Order, along with every book in The Serpent’s Series, to all thriller enthusiasts! Be sure to grab a copy of The Serpent’s Series today!
Twilight of the
Serpent
The Serpent Series Book 3
Twilight of the Serpent marks the third installment in The Serpent’s Series by S.Z. Estavillo and can be enjoyed on its own, but why would anyone want to miss out? This book is a fantastic addition to The Serpent’s Series. Like its predecessors, Twilight of the Serpent is packed with plenty of twists and turns that kept me engaged right from the beginning.
Merrick Winslow is a villain who will stop at nothing to assert dominance over everyone and everything in his life. He is a truly malevolent individual who projects his misdeeds onto others. He would commit acts and then attempt to pin the blame on someone else, insisting that it was not him but another party responsible. His only method of existence was to manipulate and gaslight those around him.
Merrick attempted to frame his ex-wife, Cheonsa, for his own actions while obsessively stalking her, seeking to regain control of their relationship and her life. It seems that his desire for control was not the sole motive; he also appeared intent on making her suffer for what he termed her transgressions.
In an effort to escape, Cheonsa goes into hiding, fleeing to Rio de Janeiro as the police begin to close in on her. There, she encounters Von Schlange, who offers her refuge and vows to assist Cheonsa in obtaining the justice she rightfully deserves.
Detective Anaya Nazario and Supervising Special Agent Blake Huxley are navigating the challenges of new parenthood. Nazario finds herself embroiled in a case concerning the deaths of two officers. During the course of their investigation, they encounter someone from their past whom they had believed to be deceased.
I thoroughly enjoyed reading Twilight of the Serpent and am eagerly anticipating the continuation of the story in the next chapter of The Serpent’s Series.

The Serpent Woman
The Serpent Series Book 2
The Serpent Woman serves as the second installment in The Serpent’s Series authored by S.Z. Estavillo, providing an excellent continuation of the narrative. The story resumes shortly after the events of the first book, The Serpent Bridge.
Similar to its predecessor, I found myself deeply immersed in its universe from the outset, captivated by the numerous twists and turns that maintained my suspense as I hurried towards the conclusion, unable to divert my gaze from the unfolding tale. I was completely absorbed from the very first page.
The narrative follows a woman who seeks justice for the innocent by eliminating those who have wronged them. She does not seem to be making a significant effort to conceal her actions, as it appears she desires the police to be aware of her deeds, albeit not her identity. After all, if they were to discover who she is, her mission, as she perceives it, would come to an end.
LAPD Detective Anaya Nazario and FBI Supervising Special Agent Blake Huxley find themselves working another case together while anticipating the birth of their child. Nazario has returned to work slightly ahead of schedule following her knee injury sustained in the previous installment, The Serpent Bridge.
Nazario and Huxley find themselves in a small condominium grappling with this case, uncertain of what justice entails in this situation. Who can be deemed right or wrong? Who are the true villains? Nevertheless, the law is the law, and they are obligated to adhere to it, correct?
I wholeheartedly recommend The Serpent Woman to all enthusiasts of mystery thrillers! Be sure to acquire a copy of The Serpent Woman today for yet another intriguing mystery to unravel!

Upon reviewing the summary for The Serpent’s Bridge, I immediately felt compelled to delve into it. However, after reading the summary, I was still somewhat uncertain about what to anticipate. I must confess that what I discovered was far beyond my expectations. It exceeded anything I could have envisioned.
The narrative of The Serpent’s Bridge is presented from multiple perspectives, which is precisely how I prefer it. This approach allows me to extract more depth from the story. Additionally, I believe that experiencing the narrative through the characters' viewpoints enhances my understanding of them.
The Serpent’s Bridge spins a dark and captivating yarn. I was thoroughly engrossed by the constant flow of twists and turns, which propelled me through the pages. The author masterfully weaves an intricate web of interconnected lives, making the challenge of deciphering how everyone fits together a compelling part of the journey.
