Themes
The story is largely concerned with the struggle for supremacy between humans and grendels, and more generally with the relationship between humans and our natural environment. The Avalon colonists inadvertently worsen their own predicament with their first attempts to rid the island of grendels, because they failed to fully understand the grendels' role in the local ecosystem. The book demonstrates that nature is a complex web of interdependent species, which human intervention can easily disrupt with unpredictable results. This is a theme also explored in Jurassic Park.
The book also draws from some of Robert A. Heinlein's work involving the adage "if you desire peace, prepare for war," in exploring the conflict between the civilian leadership of the colony who see no danger, and the military advisor who believes that danger always exists in the future. Cadmann is successively treated as crackpot, savior, scapegoat, and hero as the needs of the colony for his talents change.
Finally, the book explores the social dynamics of a situation where nobody can trust anybody else's judgement, not even their own. The eventual outcome of this is more fully detailed in the sequel, Beowulf's Children.

Famous quotes containing the word themes:
“In economics, we borrowed from the Bourbons; in foreign policy, we drew on themes fashioned by the nomad warriors of the Eurasian steppes. In spiritual matters, we emulated the braying intolerance of our archenemies, the Shiite fundamentalists.”
—Barbara Ehrenreich (b. 1941)
“I suppose you think that persons who are as old as your father and myself are always thinking about very grave things, but I know that we are meditating the same old themes that we did when we were ten years old, only we go more gravely about it.”
—Henry David Thoreau (18171862)
