Cambridge, 2018. Ana and Luis’s relationship is on the rocks, despite their many similarities, including their mothers who both fled El Salvador during the war. In her search for answers, and against her best judgement, Ana uses The Defractor, an experimental device that allows users to peek into alternate versions of their lives. What she sees leads her and Luis on a quest through Havana and San Salvador to uncover the family histories they are desperate to know, eager to learn if what might have been could fix what is.
Havana, 1978. The Salvadoran war is brewing, and Neto, a young revolutionary with a knack for forging government papers, meets Rafael at a meeting for the People's Revolutionary Army. The two form an intense and forbidden love, shedding their fake names and revealing themselves to each other inside the covert world of their activism. When their work separates them, they begin to exchange weekly letters, but soon, as the devastating war rages on, forces beyond their control threaten to pull them apart forever.
Ruben Reyes Jr.’s debut novel is an epic, genre-bending journey through inverted worlds—one where war ends with a peace treaty, and one where it ends with a decisive victory by the Salvadoran government. What unfolds is a stunning story of displacement and belonging, of loss and love. It’s both a daring imagining of what might have been and a powerful reckoning of our past.

Reviews
"A remarkably self-assured and thrilling debut novel...The book starts with a Cambridge couple whose relationship is on the rocks, until one of them decides to explore all the alternate storylines her own ancestors could have lived, bouncing from Cuba to El Salvador to the US. War, revolution, forbidden loves, and complications abound, and the result is a deliriously fun read." — Boston Globe
"Marvelous....Reyes powerfully excavates the rippling effects of the Salvadoran civil war on his characters. Equally remarkable is his depiction of tech’s alluring yet dangerous frontier, which also affords the narrative a bit of fun. Readers will be riveted." — Publishers Weekly (starred review)
"Pitch-perfect dialogue, propulsive prose, fast-paced flashbacks, and epistolary interludes....A gripping family history with a fresh speculative edge and timely resonances with the currently unfolding timeline." — Kirkus Reviews (starred review)
"Reyes mixes historical fiction and sci-fi, arguing that the choices we make in this life are the ones that matter and that love can cross generations and time. Recommended for those interested in left-wing revolutions, alternate history, and family dramas and for readers of Gina María Balibrera and Colson Whitehead who want to view the meaning of romance from many angles." — Library Journal (starred review)
“Excellent.” — BookPage
"Archive of Unknown Universes is a rare, unforgettable feast of a novel: a love letter, a lamentation, a wish. A technology-infused, literary-historical sliding doors about revolution and empire, what we leave and what we keep, family secrets and the infinite possibilities of interrupted love. Ruben Reyes Jr. is an important writer of brave and tender imagination; we are lucky to live in his timeline." — Katie Gutierrez, bestselling author of More Than You'll Ever Know
"Pay attention, world: Ruben Reyes Jr. has written a novel of deep conviction. Archive of Unknown Universes is a playful, inventive, and deeply empathetic debut novel about the meaning of borders and belonging.

"A deliciously written novel with rich history, memorable characters, and heart." — Debutiful
"This is a genre-blender exploring displacement and loss, but also belonging and love, and one that asks big questions about what could have been." — Bookriot
