Hot Air is the seventh Edgar & Ellen book and the first of the Nodyssey series.
Things have changed for Edgar and Ellen. With Augustus Nod back from the dead and the Knightleighs in disgrace, the good citizens of Nod's Limbs don't merely tolerate pranking, they embrace it. They've even made the troublesome twins local heroes. Great, right? Well, maybe not. Edgar and Ellen could be losing their edge just when they need it most. The outcome of the first-ever Nod's Limbs Knightleigh-less mayoral election is in their hands... and perhaps of slightly greater importance, the future of the planet. Humanity's safety rests in the secret of the balm, which may have just fallen into the wrong hands. Is it the twins' old nemesis, The Mason? Or the mysterious Man in the Paper Bag Mask? Or someone even more frightening?.
