The fourth installment of Dennis E. Taylor’s Bobiverse series follows a fractured fleet of sentient clones on a quest to solve a century-old mystery and unearth a discovery. The Bobiverse is on the brink of chaos as civil war brews, and the fate of one of their own hangs in the balance.

More than a century ago, Bender embarked on a mission to the stars and vanished without a trace. Despite efforts to track him down, his disappearance remains an unsolved mystery. Now, Bob is rallying his allies to uncover the truth of what happened to Bender. This isn’t just a search for one lost Bob; it’s a mission that could redefine the future of the Bobiverse altogether.

Generations of replication have fractured the once-unified Bobs into an array of personalities, with some so far removed they might as well be strangers. While a few support Bob’s quest, others see an opportunity to push their own agendas. As tensions rise, internal conflicts threaten to spill over, putting Bob’s mission and the stability of the Bobiverse in jeopardy.

Bob follows the trail left behind by Bender, only to uncover an enigma. What they find could either be their salvation or a danger they face.
