Osiris

"Rising high above the frigid waters, the ocean city of Osiris has been cut off from the land since the Great Storm 50 years ago. Most believe that Osiris is the last city on Earth. Adelaide is the black-sheep granddaughter of the city's Architect. A jaded socialite, she wants little to do with her powerful relatives--until her troubled twin brother disappears mysteriously. Vikram, a third-generation storm refugee, sees his own people dying of cold and starvation. He hopes to use Adelaide to bring about much-needed reforms--but who is using whom? As another brutal winter brings Osiris closer to riot and revolution, two very different people attempt to bridge the gap dividing the city, only to find a future far more complicated than either of them ever imagined."--Amazon.com.
