Debi Gliori 
Deep Trouble [EPUB ebook] 

When the Strega-Borgias return from holiday to find that their faithful family retainer, Latch, has collapsed from unknown causes, it is only the start of their problems. Signora Strega-Borgia is feeling very peaky in the mornings, Titus is trying to save the world and Pandora has an embarrassing crush on the new butler (to say nothing of the fact that a demon is trying to invade Strega Schloss). Only Ffup the dragon is truly happy, due to her forthcoming marriage to the Loch Ness Monster. A fantastically epic plot, culminating in Flora Mc Lachlan making the ultimate sacrifice, which will have committed fans and newcomers turning the pages late into the night.
