Good! I've actually already bought extra copies for the children's sections, so I'm quite relieved. One member of staff - a Doctor Who fan - felt that they were fine for children, but another, also a fan, thought they weren't. (Perhaps they were basing their judgement on different titles.) I think the only thing liable to prompt complaints from irate parents would be sexual references or swearing, since these can easily jump out at them during a brief scan. A book with sustained "challenging" subject matter, dealing with issues likely to go over the heads of most children, is hardly likely to raise an eyebrow, even though such a book might actually be less suitable for children.

I also suspect that many parents are likely to think that Doctor Who = Children's, so it wouldn't even cross their minds that anything in there might not be suitable. Which, I suppose, means that I have a ready-made defence if anyone complains...
