About The Serpent’s Bridge:
In a city shadowed by fear, a ruthless serial killer targets undocumented immigrants, exploiting their invisibility to evade justice. Detective Anaya Nazario faces a daunting challenge: solving a seemingly unsolvable case while battling bureaucratic obstacles and a relentless ticking clock. As she delves deeper into the investigation, Nazario discovers that the recent immigrant deaths may be connected to a haunting cold case: her own father's unsolved murder from 24 years ago.

About The Serpent Woman:
Von Schlange, the Serpent Woman, is a relentless force of vengeance, hunting predators who hide behind wealth and power. With cold precision, she delivers justice where the system fails, leaving bodies—and messages—in her wake.
Detective Anaya Nazario and FBI Special Agent Blake Huxley are on her trail, but with Nazario carrying their first child, the stakes have never been higher. As the lines between law and justice blur, Nazario is forced to ask: is Von a murderer, or the reckoning the world needs?
One enforces the law. The other rewrites it. Their collision is inevitable.

About Twilight of the Serpent:
When a decorated Army officer accuses his ex-wife of stalking him, no one doubts his word—until two cops turn up dead, shot with her weapon. Framed and on the run, Cheonsa Soo-Min flees to Brazil, where she’s taken in by Von Schlange, the vigilante the world thought was gone for good.
Von has traded revenge for a quiet life. But as Cheonsa’s story unravels, the truth points to a different kind of predator—one protected by rank, buried deep within military leadership.
Back in L.A., Detective Anaya Nazario is pulled from maternity leave to investigate the same officer deaths. What begins as a routine case quickly uncovers a far-reaching conspiracy—where justice is compromised, and the chain of command hides a killer.
As two timelines collide, justice becomes a razor’s edge.
And this time, Von isn’t just hunting.
She’s settling the score.
And this time, Von isn’t just hunting.
She’s settling the score.
Please Order: Twilight of the Serpent.

PROFESSIONAL CONTENT DIRECTOR, CREATOR, SENIOR WRITER, & BIPOC THRILLER AUTHOR
Hi, and welcome to my portfolio. My legal name is Sonyo Zofia Gray, but S.Z. Estavillo is my author’s pen name. I’m a professional content director, creator, and writer. My specialty is directing content from concept through completion. I have extensive professional writing experience that marries well with content direction, management, strategy, and social media marketing. The content creation, production process, and utilizing social media for marketing are what I absolutely love to do. I not only direct, write, and create multimedia + social content for companies but also in my free time because it is my passion.
Leadership and communication are my strengths, in addition to working collaboratively with marketing, creative, PR, and sales teams for brand building. I’ve authored hundreds of articles for a wide variety of businesses (news articles, a community magazine, lifestyle & fitness products, baby & feminine hygiene products.) Most recently, I was in charge of all content for a women’s health product that was #1 in the country and a national brand in major retail stores such as Target, Walmart, Walgreens, CVS, Costco, Sam’s Club, BJ’s, and more. I’ve written news articles, blogs, social media posts, programmatic ads, marketing copy, press releases, white papers, LinkedIn business pages, Amazon product business pages, Amazon ads, product packaging inserts, and packaging copy. My digital marketing, branding, and content leadership helped a company boost sales by 25-30%, prompted a lift in email signups by 65%, increased brand awareness by an astonishing 80%, and facilitated in the successful sale of my company for a $110 million.
Aside from being a lover of storytelling and words, I’ve created video content as well, having directed, produced, and edited (via Adobe Premiere) short-form docu-series and marketing reels for companies. My professional volunteer work also includes critiquing long-form manuscripts (novels) for aspiring as well as published authors for a literary agency to improve the story and its salability. I’m proud to have also been a former part-time editor for the Writing Day Workshop, a hub that manages nationwide virtual and in-person writing conferences. The experience has enabled me to participate as an editor at numerous writing conferences. I have critiqued and edited manuscripts from aspiring authors throughout the United States and worked in conjunction with Director Brian Klems, former columnist and editor of Writer’s Digest. I also taught a class on how writers can leverage social media to build their author platform at the Los Angeles Writers Conference this past May 13th, 2023. I also taught the same class to the North Texas Romance Writers (NTRW) July 2024.
Honing my craft as a professional writer and an editor enabled me to use these same copywriting, proofreading, and editing transferrable skills within the marketing digital space, as good content always hinges on a well-crafted story that sells products. One valuable experience I learned when editing aspiring authors’ first chapters of their manuscripts was that compelling storytelling that hooks readers is necessary for all writing, whether it be long-form fiction books or short-form marketing copywriting.
I’m always creating, writing, and, yes, posting on social. As a creative professional and one who has been hired to manage social, I have my own successful personal social media accounts with more than 90,000 authentic followers across multiple platforms to reflect my social media expertise. When I’m not creating multimedia or short-form content for companies, I’m writing long-form manuscripts. As a thriller author, I’ve completed six novels, two of which are getting published and a third in the series is currently being written.
Some of my guilty pleasures are watching true crime shows, eating tons of sushi, and reading a wide variety of genres as a multi-genre reader. I can never get enough of all three.
