In a world where global power has shifted east and revolution is brewing, two women embark on vastly different journeys—each harrowing and urgent and wholly unexpected.

When Meena finds snakebites on her chest, her worst fears are realized: someone is after her and she must flee India. As she plots her exit, she learns of the Trail, an energy-harvesting bridge spanning the Arabian Sea that has become a refuge for itinerant vagabonds and loners on the run. This is her salvation. Slipping out in the cover of night, with a knapsack full of supplies including a pozit GPS, a scroll reader, and a sealable waterproof pod, she sets off for Ethiopia, the place of her birth.

Meanwhile, Mariama, a young girl in Africa, is forced to flee her home. She joins up with a caravan of misfits heading across the Sahara. She is taken in by Yemaya, a beautiful and enigmatic woman who becomes her protector and confidante. They are trying to reach Addis Abba, Ethiopia, a metropolis swirling with radical politics and rich culture. But Mariama will find a city far different than she ever expected—romantic, turbulent, and dangerous.

As one heads east and the other west, Meena and Mariama’s fates are linked in ways that are mysterious and shocking to the core.
