Book Heaven's River: Bobiverse — Dennis E. Taylor

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 daring mission to the stars and vanished without a trace. Despite relentless 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, no matter the risks. But 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 a dizzying 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. And as tensions rise, internal conflicts threaten to spill over, putting Bob’s mission and the stability of the Bobiverse in jeopardy.
Undeterred, Bob follows the elusive trail left behind by Bender, only to uncover an enigma beyond anyone’s wildest imagination. What they find out there could either be their salvation or the greatest danger they’ve ever faced.
This thrilling, groundbreaking installment of Dennis E. Taylor’s Bobiverse saga explores loyalty, identity, and survival colliding on an epic scale.
