Followed by: The ever cruel kingdom.

"After an ancient prophecy is betrayed, a world ruled by a long line of goddesses is split in two--one half in perpetual day, and the other in an endless night--and two young twin goddesses set out on separate and equally dangerous journeys to the Breach that divides them, hoping to save their broken world."-- Provided by publisher.

Generations of twin goddesses ruled Aeon-- until one sister's betrayal defied an ancient prophecy and split their world in two. The planet ceased to spin, and a Great Abyss now divides two realms: one cloaked in perpetual night, the other scorched by an unrelenting sun. While one sister rules Aranth, a frozen city surrounded by a storm-wracked sea, her twin inhabits the sand-locked Golden City. Each goddess has raised a daughter, and each keeps her own secrets about her sister's betrayal. Now shadowy forces begin to call their daughters, Odessa and Haidee, back to the site of the Breaking. The two-- along with a healer from Aranth, and a mouthy desert scavenger-- set out on separate journeys, desperate to heal their broken world. -- adapted from jacket
