: Hey Liz, are Malone, Roxton, and Summerlee in the other novels too? Or does Challenger aquire a new set of companions in each book? Thanks for the info, I've yet to get read the first novel but one of these days I'll get around to it. :)

They're all in The Poison Belt - along with MRS Challenger! The story takes place on the" third anniversary of their great adventure on the plateau". Malone is in When the World Screamed - don' t know yet about the other two stories. Will keep you informed!
