Siyon Velo, Dockside brat turned petty alchemist, scrapes a living hopping between the planes to harvest ingredients for the city's alchemists. But when Siyon accidentally commits and act of impossible magic, he's catapulted into the limelight - which is a bad place to be when the planes start lurching out of alignment, threatening to send the city into the sea. It will take a miracle to save Bezim. Good thing Siyon has pulled off the impossible before. Now he has to master it.
