Rising Night — Meg Hendry

Holt Marius believes the time has come for Discidium to have their vengeance against Infernalis, and for Discidium to take back Vitrum. Holt will stop at nothing to gather power, even if it means going to the depths. Vetus and others gather to stop him, but he's far from the only threat Infernalis face. The people of Fortius have seen those influenced by the depths are dangerous, including Infernalis.
