Though May Northcott's heart belongs to Gabriel Tauhou, leader of the silver dragons, being stuck in Abaddon has significantly cooled down her love life—especially since a demon lord is trying to woo her. So far, May has resisted his efforts, but it's getting increasingly harder to thwart disaster.
So May is shocked when Gabriel encourages her to give in to the demon prince as part of his plan to free her in a plot so complicated, it involves her scatterbrained naiad twin, hostile dragons, and a missing relic of immense power. But it's the unknown threat that emerges from the shadows, bent on destroying May, that throws their plans into chaos.
With the dread lord long thought dead setting his sights on May and Gabriel, time is running out. Will a deal with the devil make life heaven or hell?
