"For 50 years the ocean city of Osiris has been cut off from the rest of the world, the Great Storm having left the city isolated, possibly the last surviving metropolis on the planet. Adelaide Rechnov, wealthy socialite and granddaughter of the Architect, spends her time in pointless luxury, rebelling against her family in a series of jaded social extravagances and scandals until her twin brother disappears in mysterious circumstances. Vikram Lee lives in the Western Quarter, home to the poor decedents of storm refugees and effectively quarantined from the wealthy elite. His people live with cold and starvation, but the brutal winter coming promises civil unrest, and a return to the riots of previous years. Brought together by circumstance and fate, these two very different people attempt to bridge the divide lurking at the heart of Osiris, but who is using whom, and what secrets will they uncover?".
