In this chapter book, the Subject Scouts set sail to scout whales in a boat made entirely of volcanic glass, courtesy of one alien on their spaceship named Volsprey. Volsprey is a Lavork from the planet Moltrun, a world that is covered with volcanoes. Lavorks look terrifying, and they drink lava instead of water. How will the whales react to the Scouts' Lavork-made boat?
