"Caverns" is the first book in a (currently) four book series by Mr. O'Donnell. As the title implies, the focus is on a character named McGill Feighan. In this first book, the origin of McGill and the start of his adventerous life is revealed. "Caverns" is at first a light-hearted read, but you soon find yourself drawn into the life of the hero, his triumphs and despair. McGill is a "flinger", a person who can teleport anything (himself, other people, things) anywhere that he's been before. But even for a flinger, he does not lead a normal life due to unusual events in his life, when he was a newborn. Much of the story revolves around McGill's growing-up and learning to deal with his powers, as well as the assortment of people and aliens that take an interest in his life (both good and bad).
