THE FIFTH THRILLING INSTALLMENT OF DENNIS E. TAYLOR’S BOBIVERSE SERIES CATAPULTS THE SENTIENT CLONES INTO THEIR MOST PERILOUS ADVENTURE YET, CONFRONTING FRACTURED ALLIANCES, RUNAWAY AI EXPERIMENTS AND A GALAXYSHAKING MYSTERY THAT COULD TOPPLE EVERYTHING THEY’VE WORKED TO PROTECT.

Life after the Starfleet War is anything but simple for the Bobs. Gone are the days of endless debates and camaraderie in a unified moot. Now they’re spread thin across the cosmos, grappling with interplanetary mistrust, brewing anti-Bob sentiment and the unpredictable antics of the Skippies, who
are tinkering with something dangerously close to an AI apocalypse.

Just when some Bobs start longing for a quieter life, Icarus and Daedalus return after a 26,000-year mission to the galactic core with news that rocks the Bobiverse. Their findings might hold the ultimate answer to the Fermi Paradox – but solving one of the universe’s deepest mysteries comes with a price. What they’ve uncovered is more than a revelation; it’s an existential threat that could upend everything.

From laugh-out-loud moments to thought-provoking dilemmas, the Bobiverse continues to deliver its trademark mix of humour, heart and high-stakes adventure. Will the Bobs rise to meet their most formidable challenge yet?
