Laney Alberts and Jason Magnus are finally bonded. Unfortunately, they still haven't unlocked the Luminance-the key to beating their enemy, Eris, the goddess of discord. Before they can even attempt such a feat, Zeus orders them to free Themis, the Titan goddess of justice from Tartarus. Themis is necessary to reestablish the tenuous balance in both the Mortal and Immortal worlds. The dangerous journey into Tartarus isn't their only problem. The pair face a host of new creatures set on the couple's demise. Laney and Jason must avoid these beings, the dangers of Tartarus, and summon the Luminance in order to beat Eris once and for all. Good and evil will finally face-off in a battle to determine victory or chaos. Welcome to the conclusion of the Immortal Dreams Trilogy.
