**The author of How to Train Your Dragon returns with the final,
magical installment of the New York Times bestselling Wizards of Once
series!
**Xar and Wish are on the final leg of their journey -- first stop: The
Mine of Happiness. Here, starvation is never far away for the Magical
creatures who toil in its horrible depths. Xar and Wish must escape and
fast; Xar needs to take control of his ever-growing Witchstain, and Wish
must achieve her Destiny. But the Tazzelwurm is in their way, a
grotesque monster who threatens to block every entrance.
Time is not on their side, but the forests are calling them. Will their
combined strength be enough for the biggest quest so far: to defeat the
Kingwitch once and for all?
