Farview by Kim Fielding

Ravaged by a horrific experience, Oliver Webb flees the smog-bound city of Greynox for a quiet seaside village and the inheritance he’s never seen: a cottage called Farview. He discovers clear skies, friendly imps, and a charming storyteller named Felix Corbyn.
With help from Felix’s tales, Oliver learns surprising secrets about his family history and discovers what home really means. But with Felix cursed, Oliver growing deathly ill, and an obligation in Greynox hanging heavy around his neck, it seems that not even wizards can save the day.
Still, as Felix knows, stories are the best truths and the most powerful magic. Perhaps the right words might yet conjure a chance for happiness.
