Publisher's blurb: Stone “islands” formed of stone and covered with bones of fallen gladiators rise above ink black mounds of skeletons below. Corals and seaweed grow on the structures while fish dart amongst them. Far above a skeleton throne overlooks this underwater arena. Steel spikes and sharpened stakes line the walls, preventing gladiators from climbing to escape. Two stairwells lead down to the arena, sealed with barred gates. Stone pews overlook the arena for a bloodthirsty audience, alongside more skulls. Many have died here, and many more will continue to do so.
