Finding The Remote Of Life
What if the control you have been searching for was never truly lost - only buried beneath habit, fear, expectation, and noise? Finding the Remote of Life is a reflective journey through the familiar buttons of human experience: Pause, Rewind, Fast Forward, Mute, Volume, Power, and more. With honesty and compassion, Paul Wamaria explores how our patterns, relationships, uncertainty, and exhaustion shape the lives we live - often before we consciously choose them. This book does not promise total control. It offers something more honest: the awareness to recognize what is happening, the courage to choose your response, and the presence to participate fully in the life already unfolding. For anyone who has felt stuck, overwhelmed, disconnected, or unsure of the next step, Finding the Remote of Life is an invitation to slow down, look beneath the cushions, and rediscover where your power still lives. You are not outside your life, searching for the right button. You are already here.

As Brian fights to reclaim his life, an unexpected alliance begins to uncover the truth behind the crime—one that leads to greed, betrayal, and a secret worth killing for. Just when the truth finally surfaces, it slips away again… leaving Brian trapped between justice and silence. In a story of loss, resilience, and redemption, What Remains After asks a haunting question: When everything is taken from you… what remains?

The Curated Ruin
A psychological art thriller about perception, authorship, and the violence of being seen She knew it was wrong before she understood why. Not the body. Not the blood. The composition. When art restoration student Elena Vieri steps into her mentor’s studio, she doesn’t find a crime scene. She finds a decision. Everything is placed. Every detail deliberate. The silence itself feels arranged. Someone didn’t just kill him. Someone composed him. That’s when she meets Lucien. He isn’t there to investigate. He’s there because something has already begun. Across Europe, deaths are being staged—not hidden, not disguised, but constructed. Scenes that feel too precise to be random. Too intentional to be chaos. Someone is building something. Not a pattern. A collection. And Elena is no longer outside it. She is learning to see what others can’t— the fractures beneath surfaces, the absences where something should exist, the quiet places where truth has been rewritten. The more she understands, the more dangerous she becomes. Because this isn’t about art. It’s about authorship.
