The Web Between the Worlds

The novel tells the story of Rob Merlin, the best engineer who has ever lived. His machine, the "Spider," extrudes graphite cables of incredible strength. Darius Regulo has a monopoly on space mining, and doesn't like rockets. Half of their fuel is used to lift the other half, a waste of energy. Regulo wants to build a space elevator, and hires Merlin to do it. Merlin will need to modify his Spider to extrude pure silicon cables, and to work in space.

As work progresses, Merlin becomes convinced that his parent's accidental deaths, when he was a child, were in fact murders. He comes to this conclusion based on conversations with Regulo's people he meets in the course of the project.

The questions of who, and why, become urgent as Merlin becomes certain that his life is in danger.[3]

This novel was published almost simultaneously with The Fountains of Paradise by Arthur C. Clarke. Through an amazing coincidence the two novels contained many similarities. Both protagonists are engineers who have built the world's longest bridge using a machine named the "Spider", both of whom are hired to build a space elevator, and both engineers modify their Spiders to produce a crystalline fiber.

When Baen Books reprinted this novel in 2001, they included an open letter that Clarke wrote in 1979 when the novel was first published. Clarke reassured the world that this similarity was, "A clear case of plagiarism? No—merely an idea whose time has come."[4]
