In a universe where the fundamental laws of physics are profoundly different, the monumental spacecraft *Peerless* has journeyed for six generations, its inhabitants navigating an existence where time and space behave in bewildering ways. Their mission: to return to their home world with technology capable of saving it. However, the long voyage has fostered a disconnect, and not all aboard feel allegiance to a planet they've never known. Tensions escalate when a radical proposal emerges: to construct a messaging system capable of receiving news from the *Peerless*'s own future. While some, like Agata, yearn for validation from their ancestors and a glimpse of a triumphant return, others, led by the pragmatic Ramiro, fear that foreknowledge will paralyze their agency and lead to abuse of power. When a vote fails to resolve the ideological chasm, plunging the ship into violence and dissent, Agata and Ramiro must set aside their differences. Their only hope for peace, and for their ship's future, lies in an unthinkable journey: to a world where time itself flows in reverse, offering a profound, mind-bending resolution to their epic conflict.
Critical Reception
"The Arrows of Time stands as a formidable conclusion to Greg Egan's Orthogonal trilogy, celebrated for its rigorous hard science fiction, philosophical depth, and audacious reimagining of physical laws."
