Steph - regarding children's books, it is such a shame that these themes can no longer be used. As a child I loved Enid Blyton - I know she is disapproved of now, but, having nothing whatsoever in common with the characters (they being rich, going to boarding school, and always having handy relations in the country - me being not at all rich, going to local church primary school, and hardly ever leaving suburban London), I gobbled up the books, together with those of Malcolm Saville - I loved the idea of children managing by themselves.
My younger daughter is now very keen on the Robert Muchamore CHERUB books - I haven't read them but I understand they are all about children who are spies. I don't know how he gets round the not being able to blow your nose without an adult present culture that we now have in this country - perhaps I should read one and find out.
So many modern children's novels seem to focus on day to day "issues" - parents divorcing, etc - all of which I am sure do need to be covered, but I think children still enjoy a bit of escapism just as much as we do. It must be quite a challenge being a children's writer today, and it's maybe why some children's novels are set in the past - my daughter has also been reading Julia Golding, whose stories take place in 17th century (I think) London, so she is able to have abandoned children fending for themselves with no sign of the social services on the doorstep.
