Raised on the streets, orphan Grace Marchant has always questioned the harsh laws of the Kingdom of Rathlynn. Confronting Prince Bastien Larelwynn - keeper of a dark, golden and deadly magic - was never her plan, but when her closest friend is the next mageborn taken away to the shadowy dungeons, she has no choice but to act.

Deep in the castle, Grace discovers that the Queen of Rathlynn has a devastating plan to use the mageborn's stolen powers to cement her rule forever. Begging the coldly handsome Prince Bastien to spare her friend's life, Grace is surprised to see a flicker of compassion in his obsidian black eyes, and the fire in her blood calls out to him... but if he senses the luminous mageborn power secretly unfurling within her like liquid sunlight, it's only a matter of time before she too will be imprisoned.

But Grace is shocked when Bastien, with a mysterious smile, keeps any knowledge of her powers to himself. Despite his duties to the realm, Bastien pities the mageborn, and the two hatch a plan that could change everything.

As raging fire melts blackest ice, passion and desire quickly quiet her fear and suspicion. But with her golden mageborn light growing stronger every day, Grace must ask herself if she can really trust her former enemy... and with betrayal at every turn, will they save the mageborn and get out alive?
