About the Book

In a Melbourne quantum materials lab, scientist Aisha Kade discovers evidence that should not exist: an organised interior world hidden inside a platinum ring. When the anomaly begins to communicate, Aisha and her colleagues choose caution over glory, building a first-contact protocol grounded in consent, witness, safety, and law.

The world within the ring, Isorion, is home to a civilisation that has its own councils, fears, and political tensions. Contact is possible, but only if both sides move slowly enough to avoid harm. As human researchers struggle to keep the discovery from becoming a military, corporate, or media spectacle, the ring reveals more than a single miracle. It reveals history, memory, and a system of crossings far older and more dangerous than anyone expected.

As new teams push deeper into the mystery, they uncover names, warnings, and other rooms where consent may already have failed.

Do Not Open is an adult hard science fiction novel with the urgency of a technological thriller, the emotional tension of intimate discovery, and a uniquely ethical first-contact framework at its core. It opens the Lines We Don't Cross series with wonder, danger, and a powerful question: what if the greatest test of intelligence is not whether we can cross the boundary, but whether we can refuse to?
