Louise has a mission. She has to deliver a black box through a Pacific Northwest that was ravaged by an offshore earthquake years ago. The box is seamless, with a single, blinking red light. Along the way she'll find friends and foes. Her best friend, her soul-sister Maisie, will lead the way from a Spanner-village tower. Some will not survive the journey. Their fate can change in an instant, fickle variables in an unstable equation.

Liminal is a tale of hardship and transformation. It is about nature and technology, about humans trying to find their way in an uncertain world. Even the roads are full of holes. They have to rely on their wits, trusted friends, and Louise's ancient Honda if they're going to survive.
