In a forest where magic whispers through the trees, a reluctant heir must embrace her destiny-or risk losing everything.

Seventeen-year-old Leona has always been terrible at magic. Despite her royal lineage as the future ruler of the lost forest of Caillte, she can barely conjure a spark. But when her father's insistence on her coronation thrusts her toward the throne, she faces a terrifying truth: Caillte needs a leader strong in both magic and courage-qualities she's convinced she lacks.

Desperate to prove herself, Leona and her childhood best friend Dean, a loyal knight, hatch a daring plan to steal a powerful grimoire. However, magic is unpredictable, and one reckless spell binds her fate in the most unexpected way: transforming her into a cat. With Dean and her cat Mars by her side, Leona embarks on a journey to break the curse, uncover the secrets of her bloodline, and confront the world beyond the forest.

Beyond Caillte's borders lies a kingdom ruled by humans who fear and despise mages. As Leona uncovers dark truths about her world-and herself-she must decide if she's ready to claim her power, even if it means challenging everything she thought she knew about her family, friends, and place in the world.

For fans of magical adventures, unforgettable friendships, and self-discovery, A Cat's Promise: Secrets of The Kingdom is a spellbinding tale of courage, identity, and the bonds that shape us.
