Here is the summary of the book:
When Grubb, an orphan and runaway chimney sweep, entered the wondrous world of the Odditorium, his life changed forever. Apprenticed to the mechanical marvel’s strange proprietor, Alistair Grim, Grubb unfortunately must settle into his new position on the lam, as the whole of London is convinced that Alistair Grim is a villain bent on mass destruction. Grim, however, has come up with a plan to expose the real villain: Prince Nightshade, a wicked necromancer who wants the Odditorium’s power source for himself.
With the evil prince hot on their trail, Grim, Grubb and the rest of the Odditorium's crew embark on a perilous adventure to find the legendary sword Excalibur: the only weapon capable of penetrating Nightshade's magical suit of armor. As expected, their quest turns out to be anything but ordinary. Not only can the Odditorium fly, but it can also swim! And so the crew battens down the hatches and sets off on an underwater voyage to the otherworldly realm of Avalon, home to Excalibur. Along the way, they must battle a banshee assassin, sea monsters, and a witch who seeks revenge on Alistair Grim for stealing her magical objects.
But that’s not all. Unbeknownst to Grubb and the others, their fate has been written in an ancient Avalonian prophecy—a prophecy that holds the key to a destiny not even Alistair Grim could have possibly imagined.
Of Magic, mysteries and your classic broom riding - lightning throwing witches. Of ancient lores and odder still the adventures to be had. Presenting the highly awaited sequel to the whimsically magical Odditorium series by Gregory Funaro, Alistair Grim's Odd Aquaticum. Mr. Grim, his newly discovered son Grubb (spelled like the worm with a double 'b') and all of their magical and non-magical cohorts have escaped the adventures of the first book and are very much eager for the next step.
So you know, the odditorium can fly can also disappear but did you knowm it can also swim! Yes you heard right, prepare to be amazed for their next set of palns to defeat the evil Prince Nightshade, they must journey to Avalon, the home of Excalibur. Along the way in this Odd Aquaticum, they must battle assassin banshees, wrestle with sea monsters, outwit mad witched, battle mechanical sharks and appease a tempramental goose. Just your everyday dealings at the Odditorium. With gorgeously illustrations and Funaro's words, magic is there within its pages. No matter how dire it gets, there is still always fun to be had and a solution to be infered.
But in the thicket of it all, grubb finally has found his family and learning loads under the tutelage of his father. Of course, secrets rear their heads but there are truths in them too. Alistair Grim's Odd Aquaticum was as mavelous as Alistair Grim's Odditorium was and I am very excited to know what happens next.
