Sins of Oz

Heartbreak sneaks into Lucifer and Annabelle's blissful life in the form of an old and vengeful enemy.
His actions force Lucifer into disobeying the only rule he has yet to break.
From the wide-open landscape of Dis to the gaudy lights of Kings Cross, Lucifer is forced to hunt down one nearly as powerful as he and settle a few scores along the way.
