I've met the boa from Brazil, found out what a put-outer is, and learned how Harry got his lightning shaped scar (Boo Voldemort!).
It's a pacy read - there's a lot going on, and probably made a lot easier for me by having a daughter who regards Harry Potter as one of life's essentials, rather than a luxury.
Even without reading any of the Harry Potter books, I've absorbed many Harry Potter 'truths' over the last 20 years - like muggles, potions (though I haven't come across any of those in the book yet), flying motorbikes, and owls - though I hadn't realised that owls came in flocks - my personal owl collection consists of one fluffy Hedwig - a present from Cherry - who lives on the top of my bookcase together with the rest of my furry animal collection.
I'm not bored - quite the opposite - it will be interesting to find answers to some of the things that have occasionally confused me while listening to Cherry talk about Harry Potter, both on YouTube and with her friends over the years.
