Fans of Ada Twist, Scientist, will want to join Dr. Cosmic’s class of clever monsters as they tackle gravity, comets, and many moons in the third book of the Mad Scientist Academy series. When Dr. Cosmic’s class meets Commander Nova, the school astronomer, they know their next lesson will be out of this world! With the help of Dr. Cosmic’s latest invention—a planetarium—the class must complete four challenges. Each time the planetarium shifts and the atmosphere changes, the students find themselves floating from planet to planet. They put their new magnetic antigravity belts and trusted handbooks to the test to figure out where in the solar system Dr. Cosmic’s invention has “sent” them—and how to land safely back on Earth.

With the guidance of oceanographer Professor Fathom, the class embarks on an exploration of the deep sea. Their next assignment? Identify the smallest producers and consumers of the ocean. But when a giant whale approaches the SKWID, mistaking it for an actual squid, the students must use their trusted scientific handbooks to find a way to escape the submarine and return to the undersea lab--before they become the whale's lunch! Don't miss more from the Mad Scientist Academy series!--The Dinosaur Disaster, The Weather Disaster, and The Space Disaster.
