Crépuscule d'acier

Blurb

Singularity Sky is a science fiction novel by author Charles Stross, published in 2003. It was nominated for the Hugo Award for Best Novel in 2004. A sequel, Iron Sunrise, was published that same year. Together the two are referred to as the Eschaton novels, after a near-godlike intelligence that exists in both.
The novel follows the ill-fated military campaign by a repressive state, the New Republic, to retaliate for a perceived invasion of one of its colony worlds. In actuality, the planet has been visited by the Festival, a technologically advanced alien race that rewards its hosts for "entertaining" them by granting whatever the entertainer wishes, including the Festival's own technology. This causes extensive social, economic and political disruption to the colony, which was generally limited by the New Republic to technology equivalent to that found on Earth during the Industrial Revolution. Aboard the New Republic's flagship, an engineer and intelligence operative from Earth covertly attempt to prevent the use of a forbidden technology—and fall in love along the way.
