A resourceful young heroine must protect the world from her enemies-and her own power-in this thrilling sequel to the acclaimed Breath of Earth, an imaginative blend of alternative history, fantasy, science, magic, and adventure. When an earthquake devastates San Francisco in an alternate 1906, the influx of geomantic energy nearly consumes Ingrid Carmichael. Bruised but alive, the young geomancer flees the city with her friends, Cy, Lee, and Fenris. She is desperate to escape Ambassador Blum, the cunning and dangerous bureaucrat who wants to use Ingrid's formidable powers to help the Unified Pacific-the confederation of the United States and Japan-achieve world domination. To stop them, Ingrid must learn more about the god-like magic she inherited from her estranged father-the man who set off the quake that obliterated San Francisco. When Lee and Fenris are kidnapped in Portland, Ingrid and Cy are forced to ally themselves with another ambassador from the Unified Pacific: the powerful and mysterious Theodore Roosevelt. But even TR's influence may not be enough to save them when they reach Seattle, where the magnificent peak of Mount Rainier looms.
Discovering more about herself and her abilities, Ingrid is all too aware that she may prove to be the fuse to light the long-dormant volcano ...and a war that will sweep the world.
