The Turn by Kim Harrison

#1 New York Times bestselling author Kim Harrison returns to her beloved Hollows series with The Turn-the official prequel to the series that will introduce you to a whole new side of Rachel Morgan's world, featuring Harrison's signature "spellbinding blend of sharp wit and vivid imagination" (Kelley Armstrong, New York Times bestselling author).
Can science save us when all else fails?

Trisk and her hated rival, Kal, have the same goal: save their species from extinction.

But death comes in the guise of hope when a genetically modified tomato created to feed the world combines with the government's new tactical virus, giving it an unexpected host and a mode of transport. Plague rises, giving the paranormal species the choice to stay hidden and allow humanity to die, or to show themselves in a bid to save the human race.

Under accusations of scientific misconduct, Trisk and Kal flee across a plague-torn United States to convince leaders of the major paranormal species to save their supposedly weaker kin. Not everyone thinks humanity should be saved, though, and Trisk must fight the prejudices of two societies to prove not only that humanity does have something to offer but also that long-accepted beliefs against women, dark magic, and humanity itself can turn to understanding; that when people are at their worst, the best show their true strength; and that love can hold the world together as a new balance is found.
