It’s been six weeks since angels of the apocalypse descended to demolish the modern world. Street gangs rule the day while fear and superstition rule the night. When warrior angels fly away with a helpless little girl, her 17-year-old sister, Penryn, will do anything to get her back—anything, including making a deal with Raffe, an injured enemy angel. Traveling through a dark and twisted Northern California, they journey toward the angels’ stronghold in San Francisco, where Penryn risks everything to rescue her sister and Raffe puts himself at the mercy of his greatest enemies for the chance to be made whole again.

Tras una guerra entre los humanos y las tropas angélicas, en un mundo devastado por el miedo y la superstición, unos ángeles guerreros se llevan consigo a una indefensa niña, pero Penryn, su hermana de 17 años, hará lo que sea para recuperarla.
