On the Edge of the Dark Sea of Darkness

Janner Igiby lives in a cottage above the Dark Sea of Darkness with his brother Tink, his sister Leeli, their mother, their ex-pirate grandfather, and a dog named Nugget, and mostly he wants one day where nothing terrible happens. But the lizard-like Fangs of Dang rule the town now, and the Igibys turn out to be connected to a lost king and a set of missing jewels.
