This book has been pushed back without any notice of time

On August 29, 2018, This is what Joe spoke about during an interview in Poland when Strange Weather was released there:
Originally my next book was to be a novel called Up The Chimney Down, and was to be released next year. And basically it would be real, because I’m really good at writing it. But I think the premiere will shift to 2020, because the next one will come out is Full Throttle. And this is because, as I said, in this collection will be ‘In The Tall Grass’, whose film screening will soon hit Netflix. It is logical, therefore, to preserve the collection and film, due to mutual promotion. So the premiere of the collection probably in October, and then the novel Up The Chimney Down for the autumn of 2020.
