A deadly ghost is attacking patients and threatening to bring the overworked hospital to its knees. The protective enchantments in the old Curse Ward are breaking down, leading to unusual events and supernatural sightings across the hospital. Lilith de Meath's problems only get worse as her eldest sister-and a royal pain in the ass-arrives to supervise her attempts to fix their patron Medb. Between the ghost and her overbearing sister, Lily finds her life in the City of Sorcery at a dangerous crossroads. If she can't figure out why the wards are breaking down, or a cure for her family's sickness, then being forced to return to Ireland won't be the worst thing that happens.
