The propulsive sixth installment in Dennis E. Taylor’s bestselling Bobiverse series, called “some of the best sci-fi out there” (Andy Weir, #1 New York Times bestselling author), sends the galaxy’s favorite sentient clones on a high-stakes mission as ancient mysteries, interstellar war, and civilization-shaping discoveries collide on a cosmic scale.

The Bobiverse has never been busier. As the Bobs continue expanding across the stars, a growing list of crises demands their attention. Isolated Bobs have been mysteriously vanishing with no clear explanation. The wormhole network built by the Pan Galactic Federation continues to raise more questions than answers. An abandoned alien starship holds secrets waiting to be uncovered. Tens of thousands of refugees need a new world to call home. An enemy attacking the human colonies forces the Bobs to once again meet brawn with brains. And somewhere admidst the chaos, the Bobs must race to prevent a supermassive black hole from destroying the Milky Way.

Meanwhile, Icarus and Daedalus embark on a daring expedition into the long-abandoned regions of the Pan Galactic Federation’s wormhole network. Their search uncovers evidence that the origins of the federation may be more complex than first believed, opening the door to secrets that have remained hidden for millions of years.
