So when I was little, there was this book I really loved, called Superkids by Michael Maguire. (You can tell I really loved it because I haven't read it since I was about ten and I still remember the author's name.) I can't remember that much about it, except that it was about a bunch of gifted children - were they super-clever or super-physically-gifted or something? It was published in 1978, Google tells me, and I seem to remember that it was very much that sort of 70s/80s children's superhero team grouping - a white able-bodied guy in the lead, with a mix of sidekicks involving femaleness, blackness, and disability somewhere. (Often a black female, freeing up more people to be white and male. In this case I'm pretty sure there was a black able-bodied boy and someone in a wheelchair.) Anyway, they... solved a mystery and saved the world in some way. And I think at some point in the course of events someone rode a motorbike onto a yacht. (But I just saw that happen yesterday in Tombraider 1, which I am currently playing on my ancient Playstation, so maybe I am confabulating that.) There was definitely some kind of motorcycle stunt, anyway.
Anyway, every now and then I think ooh, I'd like to read that again, but today was the first time I had that thought while being near a computer, so I had a google for it: Abebooks don't have any copies, Alibris don't have any copies, eBay don't have any copies, Amazon.com has one used copy for a hundred and eight dollars wtf (I mean, I don't think - with all apologies to Michael Maguire - that it was actually all that good. In terms of being a long-lasting children's classic or anything.) But the eBay search page (here) tells me that 'people who like Superkids by Michael Maguire' - and remember that we are here dealing with a children's thriller from 1978 - 'also like Go Fish [DVD] and Magical Moments from Great Musicals'.
So everyone else who liked it grew up to enjoy either/both lesbian independent film or musicals. That... probably explains a lot.
[ETA: An awesome person with more google-fu than me (thank you, G!) has directed me to a copy for sale for £6, so I have one on the way now! I will let you know what it's like.]
