Cassiopeia has spent fourteen years in chains, enduring everything from the darkness of the mines to the cruelty of the Unseelie King's twisted court. But now, after years of brutal servitude, she is summoned by the Dragon King and offered a single chance at freedom. The bargain is simple: solve a series of gruesome murders that have left the kingdom reeling, and in return, her shackles will be broken. But the realm teeters on the edge of ruin, whispers of a dark force returning are spreading like wildfire, and the most powerful being in the realm-the Elemental King, Hydro-has been missing for over a decade. His disappearance has left Luminalis vulnerable, and if she doesn't find him soon, everything may crumble, paving the way for the Unseelie King to march to war. With the Dragon Shifter Tirsynth, the notorious, self-centred assassin, Cassiopeia searches for the missing King and the killer while the shadows of a far darker enemy close in. But the deeper she delves into this deadly game, the more she realizes that some truths are better left buried-and that no one can be trusted.
