Bruna Machado and the Dark Side of the Net

In a world where digital justice through official means is fragile at best, Bruna Machado—a skilled cybersecurity expert—develops a groundbreaking spyware program called Bond. Determined to use her talents for good, she becomes a virtual vigilante, hunting cybercriminals and uncovering the darkest secrets hidden within the net.

But when a personal mission leads her to a disturbing case, Bruna finds herself drawn into a dangerous journey that goes far beyond the digital world. Surrounded by shadows and unexpected twists, she must decide how far she’s willing to go in the name of justice.

Bruna Machado and the Dark Side of the Net is a work of fiction—yet it touches on real-life issues that destroy lives and families every day in Brazil and around the world. This story invites readers to reflect on these harsh realities and remain vigilant about the hidden threats lurking in the dark corners of the net.

A biologist with a passion for storytelling, André Buitoni found in writing a way to merge his scientific curiosity with creativity and a deep desire to craft powerful stories and memorable characters.
In his works, he seeks to evoke a wide range of emotions in readers—blending light, relaxed moments with more intense and emotional scenes.

Beyond writing, André is also a content creator on YouTube, where he and his wife, Paula Buitoni, run the channel @familiabuitoni. Together, they share videos on travel, daily life, culture, and unique places across Brazil and beyond—always with warmth, honesty, and a touch of humor.

Whether through fiction or audiovisual content, André's goal remains the same: to inspire reflection, stir emotions, and connect with people through meaningful stories.

The Vigilantes is a collection of gripping short stories about people who have lost faith in the traditional justice system—and have decided to take justice into their own hands.

Each character in the series brings a unique perspective, shaped by personal skills, passions, and traumas. Many are specialists in a particular field—whether in technology, medicine, combat, or strategy—but all carry deep flaws and emotional wounds.

Though often heroic, they are far from perfect. At their core, they are deeply human: capable of love, fear, anger, compassion… and of crossing moral lines in the name of justice.

These stories invite readers to explore ethical dilemmas, inner conflicts, and the cost of vengeance—while reflecting on the world we live in.
