Definitely good, ticks all the boxes, but it wasn't as good as I might have expected.
I really liked Neverwhere by Neil Gaiman and Good Omens by Neil Gaiman and Terry Pratchett. They wrote together and continued in the Mythical-realist style but went in different directions.In this book he seems to take the whole, personification of mythical gods and forces, too seriously and it made me miss the humour of terry pratchett or even Christopher Moore.
For me there is one great mythical-realist book. Little Big by John Crowley. But, maybe coming to it from this book, one could find it long and winding and a little twee. Still, for me, it started the genre, and remains the best.
