The Flames of Hope (Wings of Fire #15)

The Flames of Hope (Wings of Fire #15) by Tui Sutherland tells the story of Luna, who has always aspired to change the world—to fix it, to free it—even if she has never really known how.

With all of dragonkind and humankind facing mortal peril, Luna is flying back home to Pantala with a team of dragons on a daring rescue mission. She is determined to be brave and useful. However, saving a continent proves to be far more challenging than any prophecy suggests, and 'facing a great evil' certainly demands more than just the fiery silk that Luna uniquely creates.

As she battles her way to the abyss that conceals the dark roots corrupting Pantala, Luna must unearth a long-hidden secret and unite her friends, foes, and her own powers. If she fails, she won't have the chance to change the world—she will have to bid farewell to it—forever.
