I think that Black Juice, a collection of short stories with a vaguely fantasy/science fiction feel to them, might count as kids fiction, since the protagonists in most of the tales are children – well apart from the one that’s an elephant.
I found the overall collection a bit hit and miss. It opens quite strongly with Singing My Sister Down set at a tar pit. The tale involving elephants is also quite enchanting. And the Wooden Bride is also good, while Red Nose Day was michievously funny. But some of the stories I wasn’t as enamoured by.
Author, Margo Lanagan, is certainly incredibly imaginative, and I’d be curious in reading a full novel set in one of these worlds.
