On a daring quest to prove her worth, Gwendolyn, the spirited youngest sister of the fairy royal family, sneaks into the mortal realm and finds herself captivated by a mortal prince, Kelvin, whose fate becomes strangely intertwined with her own. As the fairy kingdom fractures under the weight of betrayal, Gwendolyn faces an even greater challenge: she undergoes a mystical rite called the Change, transforming into a green snake for seven days, experiencing all the cold and hunger that mortal life brings.

Bound by ancient laws and cursed by dark magic, Prince Kelvin is trapped in a plot to force his hand in marriage. Transformed into a white hawk, he has only one week to find true love—or face a future he never chose. His only hope lies with the fairy princess who can defy the odds—and her own transformation—to save him.

In a race against time, Gwendolyn must infiltrate Queen Nefaria's enchanted court, evade the vengeful Black Opal, and reveal herself to Kelvin. In a tale brimming with courage, forbidden love, and the clash of ancient magic, Gwendolyn must discover whether love can truly transcend worlds—to save both her kingdom and her beloved prince before her time as a mortal comes to an end.

For fans of timeless fairy tales and epic romances, Gwendolyn, the Emerald Fairy weaves a spellbinding tale of destiny, sacrifice, and the transformative power of love.
