Have you been out today?

Out today, from the excellent people at David Fickling Books, and almost certainly the best children's book about a schoolgirl librarian detective to be published so far this year.

Available from at least some of the places that sell books. You've probably got a lovely independent bookshop somewhere near you staffed by lovely human beings who really like books. They'd love to sell you a copy.

Or, you know, the Internet apparently has places that sell stuff these days. Who knew? Page 45 for instance. They're awfully good.
