Celeste and the Witch Garden - Jude Gwynaire

The Witch Garden is more than just your average, typical back garden - it's more like a large and diverse, self-contained magical ecosystem, with fields, forests, rivers, villages and towns - even a castle - spread over its lush and green lands. Harper, the clumsy talking owl lives there, as do Alditha the white witch, the Green Man, and Skoros - the less than pleasant, megalomanic steampunk wizard. When a giant flying teacup appears over the Green Man's nook, Harper is convinced Skoros is up to no good, and reports the matter to Alditha. What follows is a magical adventure like no other.
