Heartbroken, bitter, and resentful, Evangeline Darrow-Frost finds herself grappling with embracing her identity as a demigoddess descended from fire. As she nurses her wounds in the aftermath from her betrothment to the once malevolent Jack Frost, no one from her time amongst the immortals seems to want to recall that the demigoddess Elle is still the Queen of Winter's Kingdom. That is, until a long-lost brother arrives to inform Elle that not all is as it seems. Enemies are afoot, still determined to ensure that the prophecy between fire and ice never becomes a reality. In the ensuing chaos of Elle's enemies returning for her, she realizes that Jack's feelings are not as estranged as she was led to believe.
