When nine year old Marley Charlotte Pennington went to stay with Grandma Grace to get to know her better, she had no idea she would also be discovering a world of magic and danger. Almost as soon as she meets her new fairy friend Lily, she learns that a bitter little mini-troll named Morton is trying to capture the fairy and force her to marry him. When Lily goes missing, Marley ends up lying to Grandma Grace to hide the truth and worries that her eight day visit won't be enough time to rescue her new friend.
