When Trajan, the wolf spider, witnesses the demise of his friend, Claudius, at the hands of a little girl and a vacuum cleaner, he realizes humans are just as terrified of spiders as spiders are of them. Trajan concocts a plan that would give his fellow arachnids free access to warm homes in which to build their webs and raise their families.

Trajan rallies the spiders, and species of all kinds gather to hear his plan to overtake the human world. The scheme is set in motion, sending people running from their homes. For a time, the spiders are content in their warm surroundings. But then discontent arises.

Trajan, a picture book for children, shares an entertaining tale about a spider's goal to rule the world.
