The Strega-Borgia children are still reeling from the shock of their nanny's disappearance at the end of Deep Trouble.

Without Flora to tend to them, the kids are growing up fast.

Indeed, Titus is in the throes of a deeply embarrassing and magically accelerated puberty, while all around the usual chaos reigns.

Baby Damp is learning to fly under the tutelage of a bat called Vesper, Ffup the dragon is struggling with the Atkins diet and Tarantella the tarantula is trying to teach her daughters the rudiments of mascara.

So far, so StregaSchloss, but add in an arrest for murder, a demon intent on revenge and a suicidal deep-frozen ancestor and you have a recipe that could only be cooked up in a Gliori-cauldron.
