Fairies aren't real...or are they? Twelve-year-old Gracie Jamison is enjoying the flowers in her family garden when suddenly, she hears a tiny voice coming from a flower and sees a small form. Gracie finds out that her garden is inhabited by garden fairies! With one wish from a new, small friend ("Why not? What could possibly go wrong?"), Gracie finds herself a fairy in a tiny, delightful world she never knew existed. But when Gracie is left a fairy permanently, she must find a way to get back to her family. The situation worsens when the entire garden begins to die. Gracie discovers it's up to her to save the garden... and every fairy in it.
