"A zany, original historical fantasy" Sunday Telegraph "Joan Aiken is the best contemporary writer of historical-fantasy we have - and I would not make such a generalisation lightly. This is a quite exceptional book." Susan Hill "Altogther an invigorating book, in which the wit and nonsense make such a sparkling fizz together that it is hard to tell one from the other" Times Literary Supplement "A writer of wild humour" Oxford Companion to Children's Literarture
