Rescue from Zoron

Mark Foy has returned home from his surprising trip to Planet Zoron. Prince Zincor’s throne is safe. But is it? Who shows up but Zincor’s Uncle Blaylock, still determined to take over Zincor’s throne, and his partner, the evil scientific genius Fentar? They’ve been mistakenly transported to Mark’s very neighborhood by the Tappa Ray and now have Mark in their sights, certain he knows something they don’t—the way back to Zoron. Blaylock’s quest for Prince Zincor’s throne is not over!
