While I didn't totally get into this book, I can't help feeling there's a lot of depth beneath the surface of the two main characters -- Daisy and her mum.
Daisy's the storyteller. She's been grounded and we only find out why later. She also keeps disappearing at the end of the early chapters, and the reason for this ties in to why her mum's grounded her. Small spoiler: she picked up a lolly from the pavement, sucked on it and got a stomach bug. Her mum was so angry that she grounded Daisy, who now has what she calls 'the gurgles' and keeps needing to run off to the toilet.
The way Daisy talks about her knowledge of things and many discoveries of little problematic bits and bobs in life is to say: 'The trouble with...', followed by the thing. Maybe I'm just being boring but I found this a bit irritating. Still, everything about the story builds a picture of a young girl's upbringing that isn't totally peachy. While Daisy and mum are getting along fine by themselves, you sense the strain on her mum towards the end, needing to sleep for at least four hundred years. Another spoiler: Daisy's father died when she was young, so she has no memory of him. But I instantly felt for her mum, having to bring up Daisy solo.
It's a good story overall. The only big thing that I didn't like was the odd switch of perspective to a little spider (who it turns out was Daisy's friend all along) who starts narrating the story towards the end. Why? Again, I guess I'm just being boring, looking for logic rather than going with the flow. (There was zero logic in Dog Man and I lapped it up.) But then that's the point isn't it? You set the rules and parameters of your story world early on and if it deviates, it can be jarring.
