Mark has always known how to disappear.

He doesn't stay long enough to matter. He doesn't let people close. And he never interferes more than absolutely necessary.

Until one night, when he makes a single decision he can't take back.

After that, the world begins to react.

Time no longer lines up the way it should. Accidents happen with unsettling precision. Warnings arrive before events unfold. And Mark begins to realize that every act of closeness triggers a consequence ? not for him, but for those around him.

The closer he gets, the faster things escalate.

As Mark struggles to understand what he's become part of, he faces a terrifying truth: saving people doesn't erase harm ? it only redirects it. And distance may no longer be enough to protect anyone.

The Cost of Closeness is the first book in Proximity, a psychological suspense series blending urban mystery, speculative tension, and emotional depth ? where connection itself is the most dangerous choice.
