Three millennia ago Solomon imprisoned seventy-two demons to protect the world from their arrogance; in the present day, Lucifer has broken the seal and commands the freed horde against Solomon's descendants. The ring—passed to Lily by her dying grandfather—should be her weapon, but its power refuses to wake. Three fire-aspected demons of the original seventy-two defy Lucifer's orders and come to Lily's defense instead. This fire-element volume follows six routes across three combustible demon companions, each shaped by the flame that distinguishes them from the water, wind, and earth volumes of the series.
