My advice is this. For Christ's sake, don't write a book that is suitable for a kid of 12 years old, because the kids who read who are 12 years old are reading books for adults. I read all of the James Bond books when I was about 11, which was approximately the right time to read James Bond books.

Terry PratchettThe truth is that even big collections of ordinary books distort space, as can readily be proved by anyone who has been around a really old-fashioned secondhand bookshop, one that looks as though they were designed by M. Escher on a bad day and has more stairways than storeys and those rows of shelves which end in little doors that are surely too small for a full-sized human to enter. The relevant equation is: Knowledge = power = energy = matter = mass; a good bookshop is just a genteel Black Hole that knows how to read.
Terry Pratchettat least nine-tenths of all the original reality ever created lies outside the multiverse, and since the multiverse by definition includes absolutely everything that is anything, this puts a bit of a strain on things. Outside the boundaries of the universe lie the raw realities, the could-have-beens, the might-bes, the never-weres, the wild ideas, all being created and uncreated chaotically like elements in fermenting supernovas. Just occasionally where the walls of the worlds have worn a bit thin, they can leak in.
Terry PratchettThey were indeed what was known as 'old money', which meant that it had been made so long ago that the black deeds which had originally filled the coffers were now historically irrelevant. Funny, that: a brigand for a father was something you kept quiet about, but a slave-taking pirate for a great-great-great-grandfather was something to boast of over the port. Time turned the evil bastards into rogues, and rogue was a word with a twinkle in its eye and nothing to be ashamed of.
