At the time of writing, this is what you see if you search amazon.co.uk for the words badger glove puppet. One of my books - America Unchained - turns up as the fourth search result. I have no idea why.
There must be other more badger-centric books out there. Like, say, just as an example, BADGERS, by Michael Clark.
But presumably that doesn't contain the words glove and puppet and presumably mine does. (I don't recall the exact context but I'm pretty sure every book I write will contain at least some passing reference to a glove puppet. They're bound to all things considered.)
If it is to do with the content of the book then presumably this is to do with the Kindle. I think all of my proper books are now available on the Kindle which means that amazon now has the content to all of them.
But out of all the books they've kindle-ised, is mine really the only one to contain all three of those words? It doesn't work for any two word combination... if you search for Badger and Glove a load of other books show up before mine. And the same is true for Badger and Puppet and, obviously enough, for Glove and Puppet... but when it's all three, mine is the only one. Odd.
I suppose if there is a two word amazon.co.uk search that leads to only one book... well... you could call that, something, like, oo... I dunno... say, a Kindlewhack.
But I'm not going there.
EDIT TO ADD: The immediate response to this has been a mass, "ah ha... you so will go there... go on, write a sequel." The navel-gazing explanation as to why I definitely won't be doing that is here.
