Turesobei dreams of adventure and a chance to prove he's no longer a child. Wizards should be careful what they wish for.

Destined to become his clan's next and perhaps greatest ever high wizard, Turesobei feels smothered under everyone's expectations. And he's fed up with people treating him like he's still a child, especially his grandfather, the current high wizard. After foiling an assassination attempt on his treasure-hunting dad, his grandfather sends Turesobei on his father's expedition to find a powerful artifact known as the Storm Dragon's Heart. He's supposed to blow off some steam and get a dose of real world experience.

But disaster strikes, and their quest becomes a race for survival.

Aided by a sassy ninja cat-girl and a mysterious diary that transforms into a bat-winged familiar, Turesobei battles sinister cultists, vengeful spirits, and a mad wizard from a rival clan who's determined to use the artifact to destroy Turesobei's homeland.

To fail is to lose everyone he loves, but success carries a terrible price.
