Textbooks have been standard schoolroom fixtures for as long as most living citizens of this country can remember. Many turn-of-the-century students were introduced to reading through the moralistic McGuffey Readers and struggled through the rather drab and colorless pages of volumes on history, geography and civics. In contrast, today's textbooks contain not only narrative content accompanied by colorful photographs and graphics, but also section and chapter exercises that are extended through the use of worksheets and other materials. Moreover, the textbook and its related student materials are packaged together with teacher's editions and tests in grade-level sets that amount to content area programs rather than mere texts.

On its mysterious voyage through interstellar space, a massive alien starship carries its human passengers to the end of a generations-long odyssey. But the great experiment designed by the Ramans has failed, and Rama III has become a battleground. Fleeing a tyrant, a band of humans ventures into the nether regions of the ship, where they encounter an emerald-doomed lair ruled by the fabulously advanced octospiders. As the octospiders lure the humans deeper into their domain, the humans must decide whether the creatures are their allies of enemies. All the while, Rama III continues its in-explorable journey towards the node, where the climax of their voyage awaits the stunning revelation of the true identity of the beings behind this glittering trek across the cosmos.
