Book VI, Gamadin: The Wild Strain:

In Book 6 of the Gamadin sci-fi adventure Series, going home takes on a whole new meaning. After their harrowing journey to the galactic core, the Gamadin crew are returning to Earth. Millawanda is fixed. She's even more beautiful, powerful, and cooler than when she was first commissioned 17,000 years ago! Wiz has taken Cheesa and Maa Dev back to Nod. Simon has a new Julian Starr sci-fi script, and Riverstone has a part in it. All Harlowe wants to do is surf, that is, if Lu will let him. But when they drop out of hyperspace, Saturn is out of position, and the Earth is eleven years out of whack. President Delmonte has been impeached, replaced by President for Life, Nootzy Shame, Tinker and Dodger are missing, cash is no longer accepted, economic chaos is everywhere, the world is on the brink of thermonuclear war, and The Church believes the saucer is a Wild Strain of beings who have come to destroy the human race! And they haven't even landed yet!
