Control doesn't always arrive loudly.Sometimes, it waits.A woman begins to sense that something in her life has shifted - not through threats or force, but through timing, silence, and familiarity that feels unearned. Messages arrive too precisely. Absence feels intentional. Normal routines begin to narrow.At first, nothing is provable.That's the point.The Last Boundary is a slow-burn psychological thriller about surveillance without intrusion, coercion without commands, and the quiet erosion of autonomy in a hyperconnected world. As the protagonist becomes aware of the patterns shaping her behavior, she must decide what costs more: comfort or control.This is not a story about technology itself, but about what happens when observation replaces consent - and when resistance becomes indistinguishable from isolation.Unsettling, restrained, and deeply modern, The Last Boundary explores how power operates when it never needs to announce itself.Perfect for readers who enjoy: Psychological suspense without goreGaslighting, coercive control, and slow dreadLiterary thrillers that linger long after the final pageAwareness is not paranoia.And silence is never neutral.
