From audible.com:

The #1 bestselling series that Audible listeners call "wonderfully entertaining," "packed with humor, geek references and thought-provoking storylines," and performed by "a true master story teller and actor" returns as the Bobs face their deadliest challenge yet.

The Bobiverse is a different place in the aftermath of the Starfleet War, and the days of the Bobs gathering in one big happy moot are far behind. There’s anti-Bob sentiment on multiple planets, the Skippies playing with an A.I. time bomb, and multiple Bobs just wanting to get away from it all.

But it all pales compared to what Icarus and Daedalus discover on their 26,000-year journey to the center of the galaxy. Sure, it could settle the Fermi Paradox for good (and what Bob doesn’t want to solve a mystery of the universe?). But it also reveals a threat to the galaxy greater than anything the Bobs could have imagined.

Just another average day in the Bobiverse.
