"Jacob Reckless journeys to the Mirrorworld to tell his shapeshifting friend Fox that a fairy curse--a deadly moth in his chest--means he has only one year to live. The journey in Mirrorworld turns into a search against time and against a Goyl treasure hunter for an enchanted crossbow, which is known to strike down any army it faces, and less well known for its healing power when shot by a loved one"--

Beyond the mirror, the darkest fairy tales come alive. . . .

For years, Jacob Reckless has enjoyed the Mirrorworld’s secrets and treasures.
Not anymore.
His younger brother has followed him.
Now dark magic will turn the boy to beast, break the heart of the girl he loves, and destroy everything Jacob holds most dear. . . .
Unless he can find a way to stop it.
