Accused of villainy, Grim and his crew must clear his name by exposing the true antagonist, Prince Nightshade, a powerful necromancer. Their quest takes them on an extraordinary underwater voyage in the flying-and-swimming Odditorium to the legendary realm of Avalon to retrieve Excalibur, the only weapon capable of defeating Nightshade. Along the way, they face banshees, sea monsters, and vengeful witches, all while uncovering an ancient prophecy tied to Grubb's destiny. Ideal for readers aged 8-11, this book offers a fast-paced plot, rich world-building, and themes of bravery, friendship, and justice.

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.
