In response to a radio plea from Abner Perry, a scientist who with his friend David Innes has discovered the interior world of Pellucidar at the Earth's core, Jason Gridley launches an expedition to rescue Innes from the Korsars (corsairs), the scourge of the internal seas. He enlists Tarzan, and a fabulous airship is constructed to penetrate Pellucidar via the natural polar opening connecting the outer and inner worlds. The airship is crewed primarily by Germans, with Tarzan's Waziri warriors under their chief Muviro also along for the expedition.

Forget the bunny trail.…In this addition to the groundbreaking series from the legendary William Joyce, Guardian E. Astor Bunnymund is on the warpath. Pitch, the Nightmare King, and his Fearlings had been soundly driven back by Nicholas St. North and company in the first Guardians’ adventure. But now Pitch has disappeared completely—and out of sight does NOT make for out of mind. It seems certain that he’s plotting a particularly nefarious revenge, and the Guardians suspect he might have gone underground. But how can they find him there? Enter E. Aster Bunnymund, the only emissary of the fabled brotherhood of the Pookas—the league of philosophical warrior rabbits of imposing intellect and size. Highly skilled in martial arts (many of which he invented himself), Bunnymund is brilliant, logical, and a tunnel-digger extraordinaire. If the Guardians need paths near the Earth’s core, he’s their Pooka. He’s also armed with magnificent weapons of an oval-sort, and might just be able to help in the quest for the second piece of the Moonclipper. This second book in The Guardians series is about much more than fixing a few rotten eggs—it brings the Guardians one step closer to defeating Pitch!
