How to describe this without a hugely number of spoilers...
A young boy meets an odd girl, her mother, and grandmother down the lane. The boy and girl have a few misadventures, and send a naughty housekeeper away. The boy grows up.
That's pretty much what I can spoil. I think.
A short novel or long novella (about 180 pages), the book is a reasonably quick first read. Some people mentioned reading it in a sitting, I took two short evenings for a re-read, after not reading the book since we purchased it when new. The book draws you along, with short, evocative chapters. That said, this is Gaiman, and there is a density of subtle detail, easy to gloss over, and worth a reread.
How old are you really?" I asked.
Eleven."
I thought for a bit. Then I asked, "How long have you been eleven for?"
She smiled at me.
Gaiman, as often, weaves together a a world of intersecting reality and unreality - I wouldn't call the forces and players in the book 'magic' because they are appear to be much older and more subtle than such a simplistic label...
"We don't do spells," she said. She sounded a little disappointed to admit it. "We'll do recipes sometimes. But no spells or cantrips. Gran doesn't hold with none of that. She says it common."
In the course of the book, the narrator and his mysterious friend interact with forces out of of time, including a manipulative, malign intelligence that manifests itself and ingratiates its way into the narrator's family.
Powerless, the narrator makes a desperate flee to the mysterious womens' home for their assistance in dispelling the being. After consultation and failed negotiation with the being, the girl calls ethereal predators to their aid in dispatching the being.
"High in the sky they were, and black, jet-black, so black it seemed as if they were specks on my eyes, not real things at all. The had wings, but were not birds. They were older than birds,and they flew in circles and in loops and whorls, dozens of them, hundreds perhaps, and each flapping unbird ever so slowly, descended."
And then things go sideways....
No more spoilers, and you'll need to read to find out why an ocean is as large as it needs to be....
