The Wergens: a highly sophisticated alien race biochemically infatuated with humans. They crave us, they need us, while we need their technology.

Humanity does what it always does. We exploit them. Until, that is, the Wergens find a way to circumvent their addiction...

From the towering skyscrapers of Earth to the methane lakes of Titan, from the ice-plains of Pluto to distant alien gas giants with steel-crushing gravity, Wergen: The Alien Love War explores personal stories of unrequited love set against the cosmic backdrop of the conflict between the two species.

Mercurio D. Rivera's Wergen stories have wowed readers and critics alike. Now, for the first time, the full arc of the human/Wergen relations is revealed: the conflict, cooperation, love, betrayal, and more.

"Mindblowing hard science fiction" - N.K. Jemisin, Hugo Award Winning Author

"Rivera gradually introduces a surprising level of ambivalence and complexity. What initially seems benevolent becomes quite the opposite, before evolving again. There are twists followed by more twists, heightening a powerful sense of alienation and menace. The conceptual and ethical switchbacks... are dizzying." - Tor.com

"Fascinating and satisfying... exploring the nature of love. Is love something deeply spiritual or simply the result of chemical reactions in the brain?" - The Fix

"The mystery of love's origins and endings are universal for humans and aliens alike, something that transcends mere biochemistry." - Tangent Online

"Rivera has shown great invention here and written something that will touch you deeply." - SF Revu
