Starman's Quest is a science fiction novel by American writer Robert Silverberg.

The story revolves around protagonist Alan Donnell, having just turned 17 and living on a space ship for all his life.

While mankind has finally mastered interstellar travel, it is still bound to the speed of light using so-called Lexman drives.

As a result, spacefarers experience the FitzGerald contraction, aging only a couple of weeks during their flights, where—depending on the actual distance traveled—years or even centuries pass by.

Finally succeeding in retrieving crucial information and, also thanks to the wealth inherited from Max, building the Cavour hyperdrive, his maiden voyage takes him to his father's spaceship, reuniting with his brother almost 8 years later, now being twins of the same age again due to the effects of the Fitzgerald contraction.
