This novel is a unique blend of six different stories, each set in a different time and place, spanning from the 19th century South Pacific to a post-apocalyptic future. Each tale is written in a different style, reflecting the time and setting it represents, and they are all connected through shared themes and recurring motifs. The stories are nested within each other, with each interrupted by the next, only to be concluded in the second half of the book. The novel explores themes of predacity, civilization, reincarnation and the eternal recurrence of the same behaviors throughout history.

In "Sphere" by Michael Crichton, a team of scientists is sent to investigate a mysterious spacecraft discovered deep underwater. As they explore the alien vessel, they uncover a massive, perfectly spherical object that seems to possess incredible powers and the ability to manipulate reality. With their own fears and hidden desires becoming increasingly dangerous, the team must navigate the psychological and physical challenges of the sphere, questioning their own sanity and the true nature of the enigmatic object.
